Key Concepts

Number of Electrons

In a neutral atom, the number of electrons is equal to the number of protons. Electrons are responsible for the chemical behavior of the element and are arranged in electron shells around the nucleus.

Number of Protons

The number of protons in an atom is equal to its atomic number, which defines the element and its specific nuclear charge.

Number of Neutrons

The number of neutrons in an atom can be determined by subtracting the atomic number from the mass number. Neutrons contribute to the overall mass of the nucleus and play a key role in the stability of an atom.

Mass Number

The mass number is the sum of the number of protons and neutrons in the nucleus of an atom. It is important for distinguishing between different isotopes of the same element.

Atomic Number

The atomic number represents the number of protons in the nucleus of an atom. It uniquely identifies an element and determines its position in the periodic table.

Isotopes

Isotopes are variants of an element that have the same number of protons but different numbers of neutrons. This difference in neutron count results in different mass numbers while the chemical properties remain similar.
