Key Concepts

Atomic Number

The atomic number is the number of protons in an atom’s nucleus and is the fundamental property that defines the type of the atom. This unique number distinguishes one element from another in the periodic table and governs the atom’s chemical behavior and identity.

Element

An element is defined by atoms that share the same atomic number, meaning they all have an identical number of protons. Despite potential variations in the number of neutrons, which result in different isotopes, the atomic number remains the key criterion for categorizing and identifying the element.
