argon
Argon has a higher mass number which means it has more particles in its nucleus than helium so I would go with argon.
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
Potassium is an element, so the only atom in potassium is potassium.
An atom of argon has a completely filled outer shell. If you know about bonding, you will get what I mean. The argon atom does not want to give or receive or give electrons because it is already as stable as possible.
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.

Niether. In 2015, the largest known atom belonged to ununoctium.

Of the elements with atomic numbers 1-18 (Hydrogen to Argon), the element with the largest atom is any of the ones in period 3 (Sodium to Argon) (Na, Mg, Al, Si, P, S, Cl, Ar). However, Argon has the most electrons in that region, so it has the highest atomic number.
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
Potassium is a metal element. There are 19 electrons in a single atom.
NO!!!! Argon is Noble Gas. This means that it exists as monatoms. (One atom). It does not combine with anything.
