Electrons are negatively charged particles that orbit the nucleus of an atom.

Front

What is the nucleus of an atom?

Back

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

Front

What is the atomic number?

Back

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

Front

What is the mass number?

Back

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

Front

What is an isotope?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

How do you determine the charge of an atom?

Back

The charge of an atom is determined by the difference between the number of protons and electrons.

Front

What is a neutral atom?

Back

A neutral atom has an equal number of protons and electrons, resulting in no overall charge.
