Absolutely. An element is defined by the number of protons in the atomic nucleus. For example, any nucleus with a single proton is by definition hydrogen. There are, however, three different forms of hydrogen; the kind with no neutrons (which is the most usual form), one neutron (known as deuterium) and two neutrons (known as tritium). Every element has isotopes with varying numbers of neutrons.

∙ 8y agoYes. For a given element, there are different isotopes possible. That is, there will be an atom with a fixed number of protons (which determines which element we have) and a variable number of neutrons. All the atoms are chemically the same because they're all the same element, but are different isotopes of the element based on their having differing numbers of neutrons. Just one example is hydrogen. Most of the hydrogen in the universe is the kind with just a single proton in the nucleus. But some hydrogen has a neutron stuck to that proton. And in extremely rare instances, there is hydrogen with two neutrons stuck to that proton. All three are hydrogen, and all three are said to be isotopes of hydrogen.
Is the same as atoms
Wiki User
∙ 13y agoYes. When an atom has a different number of neutrons than in its natural state, it is called an isotope. Therefore, if you had an isotope of, say, carbon, which normally has six neutrons, that had seven neutrons instead, it would have the same number as natural oxygen, which also has 7.

∙ 10y agoYes!
The number of protons in one atom of an element is fixed, and is the same as the number of electrons when the atom is in its neutral state. However, the number of neutrons in atoms of a single element varies.
For example, there are three stable isotopes of hydrogen, one with no neutrons in its nucleus, one with a single neutron and one isotope with two neutrons in its nucleus.
Please see the complete list of nuclides in wikipedia for a list of all the isotopes of all of the elements. You will notice that all of the elements have a varying number of neutrons in their nuclei.

Why will no one ever find an element between sulfur and chlorine?
Elements are distinguished based on their number of protons. Chlorine has exactly one proton more than sulfur. Since there cannot be fractions of protons, there can be no element between sulfur and chlorine on the periodic table.
Are the number of protons in an element the same for all neutral atoms of that same element?
No. There are several very common cases in which the number of neutrons differs from the number of protons. For early elements (the lighter ones), the proton to neutron ratio is generally 1 to 1. For example, the common hydrogen atom always has 1 proton, and usually 1 neutron. Larger elements, such as uranium, have a larger ratio. If you have ever seen, uranium is often referred to as uranium 238, the key particle in the atomic bomb. Uranium has 92 protons, meaning the difference in mass is accounted for by 146 neutrons. So the neutron to proton ratio in this case is about 1.6. The reason that the ratio differs along the periodic table can be explained by two forces. The first is electromagnetism. You are probably familiar with this. Life particles (such as 2 protons) repel while opposite particle (such as proton and electron) attract. But remember that electrons orbit around the nucleus of an atom. The nucleus itself consists of protons and neutrons. Neutrons don't seem to matter as they are electrically neutral, but how are protons able to sit by each other so tightly packed if a powerful repulsive force exists between them? The answer to that lies in a different force that is strong enough to overcome their repulsiveness at extremely close distances. This force is actually simply called the strong force or sometimes, the strong nuclear force. This force is an attraction between protons and protons, neutrons and neutrons, and even protons and neutrons! I'm not sure how well this force is understood, but we certainly know it's there. Otherwise, it would be impossible for the elements of the periodic table to even exist due to the electromagnetic repulsion of like particles! Now as we get to bigger and bigger elements along the periodic table, there are more protons packed together in a tightly spaced nucleus of a given element. This means that the electromagnetic repulsive force is dramatically increasing simply because there are more particles to repel each other. More neutrons, then, are needed to maintain a form of equilibrium, something strong enough to bind the nucleus in place. Therefore, the ratio increases. One last note: I stated that the early elements held a one to one proton to neutron ratio in general, leaving the implication that it does not necessarily have to be one to one. This would be correct if you thought that. The hydrogen atom actually has two other known isotopes (different number of neutrons then usual). Hydrogen can have one proton and two neutrons. This compound is known as deuterium, and is part of the cause for "hard water". However, deuterium is a more unstable form and does not exist as much. Hydrogen can also exist with three neutrons, and this particle is known as tritium. It is highly radioactive due to the substantial instability that it holds. A particle of such small size is not "designed" to hold onto so many neutrons because it doesn't really need more than 1 to account for the one proton. Because of such a high instability, tritium very rarely exists at all. Hope this helped! :)
What is the name of 119 element?
The element with atomic number 119 is a theoretical element and hasn't been observed. However, it does still have an IUPAC systematic placeholder name; which is Ununennium (Uue). Only one attempt has ever been made to make this element. That was in 1985, when Calcium-48 ions were bombarded at Einsteinium-254. It was a failure. If it were to be discovered, it would be the first element of period 8 and would probably fit in under Francium.

What is the heaviest element?
What do you mean by "heaviest"? If you have a lot of feathers, it weighs more than a little bit of lead! There are two ways to answer this question. One is what is the element with the highest atomic weight, and what is the element with the highest density. The element with the highest atomic weight is the heaviest for the same number of atoms, and the most dense element is the heaviest element for the same volume of material.Uranium (U) (atomic number 92) is the naturally occurring element with the highest atomic weight. Plutonium might be argued to be the heaviest naturally occurring element, but it many scientists disregard this. A few atoms of plutonium have been detected in naturally occurring uranium, but the trace ammounts were formed by neutron capture where some neutrons released in the natural decay (spontaneous fission) of uranium were captured by some other uranium atoms and transmuted into plutonium.Ununoctium (Uuo) (atomic number 118) is the heaviest synthetic element, although only a couple of atoms have ever been made!The most dense element is osmium (Os), which a density of 22.61 grams per cm3 (which is 22.61 times more dense than water!) That's almost twice the density of lead!See the Related Question below for more information about the most dense elements.Natural, known or possible?Natural 92 Uranium Heaviest element of all those in the earth when it formed (~6 billion years ago) that has not decayed to practically undetectable levels due to a short halflife.Known 112 Copernicium This changes periodically but as of February 24, 2010 element 112 was the heaviest known.Possible ∞ "Infinitium" I see no theoretical reason limiting the heaviest element, only practical.
Have scientists ever found elements with same number of protons?
Well, when two elements have the same number of protons, they are atoms of the same element. Each element has its unique proton number. If an atom has 1 atom, it is called Hydrogen. If it has 2, it is called Helium. If it has 20, it is called Calcium. However, the number of neutrons may differ. For example, in the case of Hydrogen, it may have no neutron, 1 neutron or 2 neutrons, and still be called Hydrogen. However, they are called 'isotopes', meaning members of the same element(same number of proton), but having different neutron numbers.
Is calcuim a mixture?
Only of isotopes. Calcium is an element. No mixture of chemicals can ever be a single element. The atoms of any element, such as calcium, always have the same number of protons and the same number of electrons. The number of electrons in an atom is the same as the number of protons in that atom. Different Isotopes of an element have different numbers of neutrons in the nucleus, but this doesn't change any of the chemical properties.
Can the atomic number of an particular element ever change?
No, the atomic number of an element can't change. Because, we can identify an element by its atomic number and atomic mass. and hence they have been arranged in the periodic table on the basis of their mass number and atomic mass so , it couldn't be changed. Every element has a fixed atomic number..
Can the number of prontons in an element ever change?
Not unless it becomes another element.
How do atoms differ one another?
Atoms of different elements are different because the have different numbers of protons. The atomic number (the number of protons) is what defines which element the atom is. For example, all atoms containing 1 proton are hydrogen. 2 protons are helium, 3 lithium and so on. See the periodic table of elements for more. Atoms of the same element can still be slightly different in the number of neutrons they have; these are called isotopes. Their properties stay the same but they have different masses. You need not consider electrons too much because most atoms have a relatively loose hold on electrons and don't account for much mass BUT!!!! electron configuration is the main factor for determining how elements will react with each other.
What is the atomic number of an elementtells you number of what?
Type your answer here... Well, it tells you how many protons and neutrons and electrons are in the element. I happened to be the one that also aked this question and now it seems weird that I am also answering it! This is my first answer ever, so it means alot to me. Thank you.
How do atoms of different element differ from one another?
To understand the answer, one must understand the basic anatomy of an atom. There are three "parts" to every atom, the neutron (neutral charge), the proton (positive charge), and the electron (negative charge). Within the center of atom (the nucleus) are the neutrons and proton, and the electrons are moving around them in an "electron cloud." To clarify, let's think of an atom as the earth with the surrounding atmosphere, the land mass if composed of neutrons and protons, while the atmosphere contains ever moving electrons. Now to answer the question at hand- An element is classified by the number of proton within the nucleus; therefore, the difference between different elements is the number of protons within the nucleus.
Do the number of protons in a specific atom ever change?
no. because if the number of protons changes, then the element changes
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
Does the number of protons in mercury ever change?
No it NEVER EVER EVER EVER changes other wise it would be a completely different element like aluminum .
How many neutrons are in an atom with an atomic number of 3?
The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li. If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.
Can two atoms of same element ever have different atomic numbers?
The atomic number is identical for all the isotopes of the same chemical element.
