(Hydrogen is the only exception to this statement; most hydrogen atoms contain no neutrons.) The protons and neutrons in an atom are found in the atomic nucleus, while the electrons are found in the space around the nucleus. The number of protons in a nucleus defines an atom. Hydrogen ...
Anatomis the smallest unit of matter that contains the properties of a chemical element. This is why atoms are commonly known as the building blocks of chemistry. Atoms are composed of three types of subatomic particles: protons, neutrons, and electrons. The protons and neutrons are found in ...

Because the atomic mass is determined by the sum of the number of protons and neutrons contained in the nucleus, isotopes differ in mass. Since they contain the same number of protons (and hence electrons), isotopes have the same chemical properties. However, the nuclear and atomic properties ...
