Electricity causes the rearrangement of electrons and atoms from water molecules. Two hydrogen atoms covalently bond to form hydrogen gas. Two oxygen atoms covalently bond to form oxygen gas. There ...

Covalent bonds are strong bonds. Atoms that share pairs of electrons form molecules. A molecule is a group of atoms held together by covalent bonds. Covalent compounds do not conduct electricity.

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...
