Subatomic particles with a negative charge

Back

Electrons are subatomic particles that carry a negative charge and are found in the electron cloud surrounding the nucleus of an atom.

Front

Subatomic particles with a positive charge

Back

Protons are subatomic particles that carry a positive charge and are located in the nucleus of an atom.

Front

What are the charges of protons, neutrons, and electrons?

Back

Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.

Front

Which two subatomic particles make up the nucleus of an atom?

Back

The nucleus of an atom is made up of protons and neutrons.

Front

What does the atomic number represent?

Back

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

Front

What are neutrons?

Back

Neutrons are subatomic particles found in the nucleus of an atom that have no charge.

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 is the difference between atomic mass and mass number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while mass number is the total count of protons and neutrons in a specific isotope.

Front

What are isotopes?

Back

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

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus of an atom where electrons are likely to be found.
