Atomic Structure

Protons are subatomic particles found in the nucleus of an atom, carrying a positive electrical charge.

Electrons are subatomic particles that orbit the nucleus of an atom, carrying a negative electrical charge.

An atom is the basic unit of a chemical element, consisting of a nucleus surrounded by electrons.

Neutrons are neutral subatomic particles found in the nucleus of an atom, having no electrical charge.

Lithium is represented in the Bohr Model as having three protons and three electrons.

The nucleus is the dense central core of an atom, containing protons and neutrons.

An atom is electrically neutral when it has an equal number of protons and electrons.

The mass of an atom primarily comes from protons and neutrons, as electrons have negligible mass.

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons.
