covalent bond - Answer-The sharing of a pair of valence electrons by two atoms. (Ex: Hydrogen, oxygen, water, Methane) Polar covalent bond - Answer-When electrons are not equally shared among the atoms within a bond. (Ex: water) This causes a negative and a positive side of a molecule. Hydrogen Bond - Answer-A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bon...
