None of the elements of the Periodic Table have the same number of protons. All elements have their own unique atomic (proton) number which defines how many protons that element has in its atoms. Just a note that the atomic number is also called the proton number. To know which number is which the atomic number is always smaller. The Atomic number gives both the proton and electrion number as these most be the same due to the charges for it to be an atom.
What else can I help you with?
What is a pure substance all the atoms have the same atomic number or number of protons?
A pure substance is a material made of only one type of particle, such as atoms or molecules, and all the atoms in a pure substance have the same atomic number or number of protons. This means that all the atoms in a pure substance are of the same element.
What does the atomic number tells you about the element?
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
What causes atoms of the same elements to have different atomic masses?
Elements have a certain number of protons(+), neutrons(0) and electrons(-). The atomic number shows the number of protons and electrons in the element (has to have the same number of each to stay stable). The atomic mass shows the number of neutrons. For example, Hydrogen has an atomic mass of ~1.01 (and an atomic number of 1). That means that it has 1 electron and 1 proton but no neutron (1 proton+0 neutrons=1). Helium has an atomic mass of ~4.00 (and an atomic number of 2). That means that it has 2 electrons, 2 protons and 2 neutrons (2 protons+2 neutrons=4). Hope you can understand. :S
Can 2 isotopes of the same element differ in the number of protons?
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
How many protons and does ca plus 2 have?
The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
If you have 2 atoms have the same number of protons but differernt number what will they have the same?
They will have the same atomic number.
If you have 2 atoms have the same number of protons but different number of neutrons what will they will have the same?
No, they will not be considered isotopes since isotopes are atoms of same element (therefore, have same number of protons). However, the types of atoms which have same atomic mass number but different no. of protons, they are called isobars. Eg:- Calcium and Argon = =
How are 2 isotopes of an element similar?
Their atoms have the same number of protons and electrons and therefore have the same chemical properties. However, the atoms do differ in the number of neutrons and so their physical properties are slightly different.
Why does helium not have a charge?
all atoms generally do not have charge as the number of protons and number of electrons will be the same.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons?
They are called Isotopes
What are the two atoms that have th same number of proton called?
they are the same element because an element has an atomic number through its number of protons so if there was an element with 2 protons it would be number 2 in the periodic table which is helium, if another element has 2 protons it should be helium still, if it wasn't modified in anyway
What is thenumber of protons in oxygen?
it has 4 protons and 15 electrons!!!Ans 2.Oxygen has 8 protons.p.s. like all atoms, it has the same number of electrons as protons : 8.

How atoms of the same element can be different?
An element by definition refers to all atoms with the same number of protons; so any atom with 1 proton is the same element as all other atoms with one proton; which would be helium. And then, all atoms with 2 protons would be the same element; hydrogen. But the atoms that have 1 proton and the atoms that have 2 protons cannot be the same element.An ion is an element with a different amount of electrons, where if it is a positive ion it is missing an election compared to a "normal" element and if it is a negative ion it would have an extra election compared to a "normal" element.An isotope is a member of the same element but it has a different number of neutrons.
What are atoms with the same atomic number?
Molecules is actually an incorrect answer, as molecules are assortments of atoms that are bonded together via their electron(s) either by covalent or ionic bonds. An atomic number is a number that signifies an atoms number of protons. All elements are atoms, and there are 118 known elements, all with different atomic numbers, for they each have different amounts of protons. In essence, the atomic number DEFINES the atom, for instance Hydrogen (H+), has only one proton, while Ununotium has 118 protons. So if an atom has a different number of protons in its nucleus than another atom, then they always will be different elements. Therefore they are not "grouped" into anything other that most basically the periodic table. So to answer your question directly, there is no "group" to speak of, for all atoms with the same atomic number are essentially the same type of atom. You may have meant neutrons, as atoms that are the same but with varying numbers of neutrons can still be the same element, yet differ in neutrons in the nucleus. These are called Isotopes.
