Chemical isomers: compounds with the same chemical composition but with a different structure.
Nuclear isomers: isotopes having different half lives.
Isotopes: atoms having a different number of neutrons in the atomic nucleus.
Polymers: compounds formed from many monomers.
Molecule: an entitity formed from two or more atoms linked by chemical bonds.
hydrocarbons, they are called isomers

Chromium has 25 known isotopes, 2 isomers, 3 of which are non-radioactive.
Francium has approx. 40 isotopes and nuclear isomers.
Geometric isomers are molecules that contain the same number and types of atoms, and bonds. They have different arrangements of the atoms.
