Key Stage 4

Meaning

The Neutron is a neutral particle found in the nucleus of an atom.

About Neutrons

Neutrons have a relative atomic charge of 0 and a relative atomic mass of 1.

The number of neutrons in an atom can be found subtracting the Atomic Number from the Relative Atomic Mass.

Hydrogen	Helium	Lithium	Beryllium

This atom has an Atomic Number (Z) of 1 and a Relative Atomic Mass (A) of 1. Number of neutrons = A - Z Number of neutrons = 1 - 1 Number of neutrons = 0	This atom has an Atomic Number (Z) of 2 and a Relative Atomic Mass (A) of 4. Number of neutrons = A - Z Number of neutrons = 4 - 2 Number of neutrons = 2	This atom has an Atomic Number (Z) of 3 and a Relative Atomic Mass (A) of 7. Number of neutrons = A - Z Number of neutrons = 7 - 3 Number of neutrons = 4	This atom has an Atomic Number (Z) of 1 and a Relative Atomic Mass (A) of 1. Number of neutrons = A - Z Number of neutrons = 1 - 1 Number of neutrons = 0
