Ionic Bonding: Ionic bonding is a type of chemical bond formed between oppositely charged ions through electrostatic attraction.
Metal Oxide: A metal oxide is a compound composed of a metal cation and oxygen anions. Examples include MgO, CuO, Fe2O3.
Reactivity Series: The reactivity series ranks metals based on their tendency to lose electrons during chemical reactions. Magnesium is highly reactive and readily forms compounds like MgO.
