No.
Those are called Isotopes.
those elements are in the same 'family' or 'group'
No, those are the only numbers that satisfy the equation. x squared -2x = 0
neutral, with the number of protons equaling the number of electrons.
It is because the two numbers are the same.
Isodiapheres are nuclides which have the same difference in the number of neutrons and protons or nuclei with same neutron excess.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
