Potassium - Element information, properties and uses | …

This was the first alkali metal to be isolated, but Davy went on to isolate sodium, calcium, magnesium and barium. Whilst Davy named his new metal potassium after the potash, Berzelius, the Swedish chemist who invented the international system of chemical syols now used by chemists the world over, preferred the name kalium for the metal, better reflecting its true origins, he thought.

What causes ions to form ionic bonds? - A Plus Topper

The non-metal atoms accept the electrons donated by the metal atoms to achieve a stable noble gas electron arrangement. Thus, negatively-charged ions are formed. The positively-charged ions and negatively-charged ions are then attracted to each other by strong electrostatic forces which are closely-packed in an orderly manner in a crystal lattice, forming an ionic compound.
