Why is potassium symbol K?

The name derives from the English “potash” or “pot ashes” because it is found in caustic potash (KOH). The symbol K derives from the Latin kalium via the Arabic qali for alkali.

Which is smaller Na or Na+?

Yes Na+ is smaller than Na because Na+ is formed when an electron is lost from the Na atom,Thus the effective nuclear charge increases bcz the number of protons exceeds the number of electrons . This results in bringing the valence shell a little closer to the nucleus because of a very strong nuclear pull.
