How are molecules formed?​

Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine.

hope that helps uhh :)

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. ... In a covalent bond, electrons are shared between atoms. The bonds between the two hydrogen atoms and the oxygen atom in a molecule of water are covalent bonds
