Subatomic Particles (Physical Science)

Front

What is a subatomic particle?

Back

A subatomic particle is a particle smaller than an atom, which includes protons, neutrons, and electrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What charge do protons carry?

Back

Protons carry a positive charge.

Front

What charge do electrons carry?

Back

Electrons carry a negative charge.

Front

What charge do neutrons carry?

Back

Neutrons carry no charge (they are neutral).

Front

Which subatomic particles are found in the nucleus of an atom?

Back

Protons and Neutrons are found in the nucleus.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons.

Front

How do you determine the number of neutrons in an atom?

Back

Subtract the atomic number (number of protons) from the mass number.
