What do isotopes allotropes and isomers have in common?

Answer 1

They are all forms of a given chemical element. Example for sulfur:

- S6, S7, S7, S7, S12, S18, etc. are allotropes of sulfur; but the atomic number (number of protons and electrons) of the sulfur atoms is the same.

- sulfur has natural or artificial isotopes; but the atomic number (number of protons and electrons) of the sulfur isotopes is the same.

- an isomer is 43mS; but the atomic number (number of protons and electrons) of this sulfur isomer atoms is the same as for other isotopes.

Answer 2

Isotopes, allotropes, and isomers are all different forms of the same element or compound that have distinct atomic structures or arrangement of atoms. They have the same number of protons but differ in the number of neutrons (isotopes), bonding arrangements (allotropes), or structural arrangement (isomers).
