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.
argon
Potassium is a metal element. There are 19 electrons in a single atom.
argon atom
2 atom potassium and 1 atom oxygen
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
Niether. In 2015, the largest known atom belonged to ununoctium.
the atom you are referring to, is actually the element Argon. An element is a substance that is just made up of one kind of atom. In this case, the atom you are talking about (Argon), has 18 protons.
The largest atom of a chemical element is the francium atom - the greatest atomic radius.
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.
