the periodic law
The properties of the elements are periodic functions of their atomic numbers.
According to the Brnsted-Lowry theory, an acid is any substance (molecule or ion) that can transfer a
proton (H+ ion) to another substance, and a base is any substance that can accept a proton. Acid-base
reactions are proton-transfer reactions, as follows
