argon
K (potassium) has the larger atomic radius.
Argon (Ar) is the nearest noble gas to potassium.
A potassium atom "always" loses exactly one valence electron when it reacts with another element, because one valence electron in a potassium atom has a much lower ionization energy requirement than any other electron in the same atom. (This property is generally ascribed to the fact that when a potassium loses exactly one electron, it acquires the very stable electron configuration of the noble gas argon.) A chlorine atom has a very strong attraction (its electronegativity) for exactly one electron, which gives the charged atom the electron configuration of an argon atom. Therefore, when a potassium atom is close enough to a chlorine atom, one electron is transferred between to form an ionic bond and a formula unit of the compound potassium chloride.
Potassium element can turn into argon element only by the emission of a beta particle.

I would say no. The potassium atom has 1 valence electron which is in the 4th valence shell. To form the potassium ion, it gives away this electron - thus becoming K+. Now, it has no electrons in the 4th valence shell - they are all in the 3rd valence shell. Argon also has all of its electrons in the 3rd valence shell. Also, K+ now has the same number of electrons as Argon. The reason why, at least I would say, argon has a larger radius than K+ is that even though they are in the same valence shell and have the same number of electrons, argon has one less proton than K+. This means that argon's nucleus does not pull in its electrons with quite as much force as K+. Therefore, the electrons (on average) are not as close to the nucleus as with K+. At least, this is how I would reason this out.
Potassium is a metal element. There are 19 electrons in a single atom.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
Potassium element can turn into argon element only by the emission of a beta particle.
