Atoms are electrically neutral if they have an equal number of protons and electrons. Atoms which have either a deficit or a surplus of electrons are called ions. Electrons that are furthest from the nucleus may be transferred to other nearby atoms or shared between atoms. By this mechanism atoms are able to bond into molecules and other types of chemical compounds like ionic and covalent network crystals.
[edit] Elements, isotopes and ions
Atoms with the same atomic number Z share a wide variety of physical properties and exhibit almost identical chemical properties (for the closest instance to an exception to this principle, see deuterium and heavy water). Atoms are classified into chemical elements by their atomic number Z, which corresponds to the number of protons in the atom. For example, all atoms containing six protons (Z = 6) are classified as carbon. The elements may be sorted according to the periodic table in order of increasing atomic number. When this is done, certain repeating cycles of regularities in chemical and physical properties are evident.

The mass number A, or nucleon number of an element is the total number of protons and neutrons in an atom of that element, so-called because each proton and neutron has a mass of about 1 amu. A particular collection of a certain number of protons Z, and neutrons A-Z, is called a nuclide.

Each element can have numerous different nuclides with the same Z (number of protons and electrons) but varying numbers of neutrons. Such a family of nuclides are called the isotopes of the element (isotope = "same place", because these nuclides share the same chemical symbol and place on the periodic table). When writing the name of a particular nuclide, the element name (which specifies the Z) is preceded by the mass number if written as a superscript, or else followed by the mass number if not a superscript. For example, the nuclide carbon-14, which may also be written 14C, is one of the isotopes of carbon, and it contains 6 protons and 8 neutrons in each atom, for a total mass number of 14. For a complete table of known nuclides, including radioactive and stable nuclides, see isotope table (divided).

question is not clear, if u r asking about the element that have atoms with different number of neutrons then these atoms are known as isotopes, they have same number of protons but different number of neutrons in the nucleus
