No, they have the same atomic mass, which is the number of protons plus the number of neutrons. No two elements have the same atomic number.
Atomic number of an element is same as the number of protons. It is same as number of electrons in neutral atom.
the atomic number
In a neutral atom, the number of protons (or the number of electrons) are the same as the atomic number.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
No.
Yes, in their natural state, the proton and electron number are the same, and thus the same as the atomic number.
No - atomic number is the number of protons.
The atomic number is the same as the number of protons, ALWAYS.
