Isotopes

Page 1

Isotopes is the atoms of an element which have the same number of protons and electrons but different numbers neutrons.

Relative atomic mass is the mean mass of an atom relative to the mass of an atom. For example: Carbon has a relative atomic mass of 12.

Chlorine is split into 2 isotopes with relative abundance of 75% and 25%. It has a relative atomic mass of 35.5.

Relative atomic mass can be found by multiplying the percentage abundance of the element with the amount of neutrons available and adding them. Then dividing it by hundred.
