Key Concepts

Atomic Number

The atomic number represents the number of protons in an atom's nucleus. It defines the element's identity and, in a neutral atom, also equals the number of electrons.

Mass Number

The mass number is the total number of nucleons (protons and neutrons) in the nucleus of an atom. It is used to calculate the number of neutrons by subtracting the atomic number from the mass number.

Isotopes

Isotopes are variants of a chemical element that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference can affect the physical properties but not the chemical behavior of the element.

Atomic Notation

Atomic notation succinctly expresses key information about an atom, such as the atomic number as the subscript and the mass number as the superscript. This notation is essential for determining the numbers of protons, neutrons, and electrons in an atom.
