Definition - Isotopes

• Isotopes are the atoms of the same element with different masses are known as isotopes

• Example -: Carbon-12, Carbon-13, Carbon-14 And more of these kind of atoms are isotopes as they are the same atoms with different masses

Stable Isotopes

• Stable isotopes never decay or are not very reactive

• Example -: Carbon-12 And Oxygen - 16

Unstable Isotopes

• Unstable isotopes are the isotopes that decay really quickly and are highly reactive

• Examples - Carbon 14 Or Carbon 13
