As you can see, Lithium, Beryllium, Sodium, Magnesium, Aluminum, Potassium, and Calcium are metals out of the first 20 elements. Metals are usually ductile or malleable. The sum of the oxidation states within a compound or ion must equal the overall charge. Whilst Davy named his new metal potassium after the potash, Berzelius, the Swedish chemist who invented the international system of chemical symbols now used by chemists the world over, preferred the name kalium for the metal, better reflecting its true origins, he thought. There are deposits of billions of tonnes of potassium chloride throughout the world. They are characterized by bright luster, hardness, ability to resonate sound and are excellent conductors of heat and electricity.
