A neutron carries no charge (it is neutral).

Front

What is the nucleus of an atom?

Back

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

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

How do isotopes of an element differ?

Back

Isotopes differ in their mass numbers due to the different number of neutrons.

Front

What does the atomic number represent?

Back

The atomic number represents the number of protons in the nucleus of an atom.

Front

What is the mass number of an atom?

Back

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

Front

What is the difference between an ion and an isotope?

Back

An ion is an atom that has gained or lost electrons, resulting in a charge, while an isotope has the same number of protons but a different number of neutrons.
