Atomic Structure

Front

Subatomic particles with a positive charge

Back

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

Front

Subatomic particles with a negative charge

Back

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

Front

The smallest particle of an element

Back

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

Front

Subatomic particle with a charge of 0

Back

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

Front

What element is represented in this Bohr Model? (Example: Lithium)

Back

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

Front

The center of an atom that contains protons and neutrons

Back

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

Front

The overall charge of an atom

Back

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

Front

The mass of an atom primarily comes from which particles?

Back

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

Front

What is the atomic number of an element?

Back

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

Front

What is an isotope?

Back

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