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 else can I help you with?
Can atoms of different elements have the same number of protons be from the same element?
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
The nuclei of all atoms of a given element always have the same number of what?
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
How do you know if two atoms are from the same element?
Two atoms are from the same element if they have the same number of protons in their nuclei. This is the defining characteristic that determines an element's identity. For example, all carbon atoms have 6 protons, so any two atoms with 6 protons are considered to be the same element, carbon.
What does an element's atomic number tell us?
An element's atomic number tells us the number of protons in an atom of that element. It is used to uniquely identify the element and determine its placement on the periodic table. The atomic number also corresponds to the number of electrons in a neutral atom of that element.
How do you find out the amount of electrons in an atom?
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
Is it true that the number of protons in an element is the same for all neutral atoms of that element?
Yes, that's correct. The number of protons in an element determines its atomic number and defines which element it is. For neutral atoms, the number of protons is equal to the number of electrons, balancing out the charges and making the atom electrically neutral.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Do hydrogen and atoms have an equal number of electrons?
No. Neutral atoms of each element, including hydrogen, have a unique number of electrons, which is equal to the number of protons in their nuclei. The number of protons is the element's atomic number on the periodic table.
Where did you found in an element number of protons and electrons?
The atomic number is equal to the number of protons and electrons, for a neutral atom.
What must atoms of the same element have?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
How do you find the number of protons or electrons in a neutral atom of an element?
The number of protons in an atom is equal to the atomic number of the element, which can be found on the periodic table. Since atoms are electrically neutral, the number of electrons in a neutral atom is also equal to the number of protons.
Can the neutral atoms of tow different element have the same number of electron explain?
NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.
Is it true that the number of electrons in an element is the same for all neutral atom of that element?
Yes, this is true for electrons (and protons) of all neutral atoms of an element.
Element whose neutral atoms have twenty protons?
''CA" (CAlCiUM)
What does the atomic number of an element say about the number of particles in atoms of that element?
The atomic number is equal to the number of protons and neutrons in a neutral atom.
What are Atoms with the same number of protons are?
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
What does the atomic number tell you the number of in a neutral atom of an element?
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
