Meaning

Isotopes are atoms with the same number of protons (the same element) but a different number of neutrons.

About Isotopes

Each element has many isotopes but some are stable and others are unstable so they decay quickly into other isotopes or a different element.

Different isotopes of the same element have the same atomic number but different atomic mass due to the different numbers of neutrons.

Hydrogen-1	Hydrogen-2	Lithium-7	Lithium-6


Hydrogen always has 1 proton but in this case has no neutrons.	Hydrogen always has 1 proton but in this case also has a neutron. This isotope of Hydrogen is known as Deuterium.	Lithium always has 3 protons but in this case has 4 neutrons.	Lithium always has 3 protons but in this case has 3 neutrons.
