What are ionic and molecular compounds? Give examples.
(N/A) Molecular compounds are formed when atoms of different elements combine in definite proportions to form molecules. Examples include $H_2O$ (water),$NH_3$ (ammonia),and $CO_2$ (carbon dioxide).
Ionic compounds are composed of metals and non-metals containing charged species known as ions. An ion is a charged particle,which can be either positively charged (cation) or negatively charged (anion). Examples include $NaCl$ (sodium chloride) and $CaO$ (calcium oxide).
