Argon has a higher mass number which means it has more particles in its nucleus than helium so I would go with argon.
Argon has the larger atom compared to potassium. This is because argon has more electrons and a greater number of protons and neutrons in its nucleus, leading to a larger atomic size.
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
If HE was a compound it would be a compound of H (hydrogen) and E (sorry there is no such element).If HE is an element then it is misspelled and should be He (helium).
An element is a pure substance that is made up of only one kind of atom.Elements that can exist as a single atom are the noble gases in Group 18 of the periodic table.
Helium is an inert gas meaning that it will not combine with other elements or compounds. More specifically, chlorine will not bond with helium. But, if it did, as could happen in a supernova explosion, since chlorine is 17 on the periodic chart, and helium is 2, when they fuse they would create an atom of potassium which is 19.
Niether. In 2015, the largest known atom belonged to ununoctium.

Elements are not species. Helium is an element. Helium can be a single atom.
Helium is an element because it contains only one atom in its simplest form.
Helium is an element- the second one in the periodic table.
No, helium gas is not a compound. Helium is an element, which means it consists of only one type of atom.
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
The smallest atom is helium (nucleus and electrons) while francium is the largest. Helium: 28 picometer francium: 260 picometer
A chloride ion (Cl-) has the same number of electrons as a neutral atom of the element argon (Ar).
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.
