Key Concepts

Mass Number

The mass number represents the total number of protons and neutrons in the atom's nucleus. It is used to distinguish different isotopes of the same element that have the same number of protons but a different number of neutrons.

Isotopes

Isotopes are variants of a particular chemical element that have the same atomic number but different mass numbers because they contain differing numbers of neutrons. This difference in neutron count can affect the atomic mass and certain nuclear properties without altering the chemical behavior.

Atomic Number

The atomic number of an element is the number of protons in the nucleus of its atoms. It uniquely identifies the element and, in a neutral atom, is equal to the number of electrons orbiting the nucleus.

Subatomic Particles

Subatomic particles refer to the particles that constitute an atom, primarily protons, neutrons, and electrons. Protons are positively charged and define the element's identity, neutrons carry no charge and contribute to the mass of the atom, and electrons are negatively charged particles that orbit the nucleus and participate in chemical bonding.
