Ionic bonds form between metal and non-metal atoms
Ionic bonds form when metal atoms lose electrons and non-metal atoms gain electrons
Compounds held together by ionic bonds are called salts
Ionic bonds are very strong when the compound is dry
Ionic bonds are easily broken in water. This is why many salts dissolve easily in water to form ions
Cations are ions that possess a positive charge because they have more protons than electros. The metal atoms in a salt typically become cations
Anions are ions that possess a negative charge because they have more electrons than protons
Hydrogen bonds are fairly weak intermolecular attractions that occur between polar molecules
Because of the high electronegativity of oxygen and the low electronegativity of hydrogen, the oxygen end of the water molecule has a slight negative charge, while the hydrogen end has a slight positive charge. This gives water its "bent" shape
