A nucleus that has protons and neutons which possesses some electrons revolving around it in definite orbits... that is one atom! Each element has a generalized atom which has a definite number of protons, nucleus and electrons. read more

The difference between atoms, ions and isotopes is the number of subatomic particles. An atom is the basic building block of matter, the smallest molecule of an element that exists and that cannot be chemically divided by ordinary means. Each atom is comprised of protons, neutrons and electrons. read more

Isotopes are atoms containing the same number of protons in the nucleus ( ie the same atomic number ) but differing numbers of neutrons in the nucleus ( ie different mass numbers. Total number of protons and neutrons in a nucleus is the definition of Mass Number ). read more
