Helium does not form cation
Nuclear
The cation FeI2 does not exist on its own. Iron typically forms cations with a 2+ charge, like Fe2+, but it would not typically bond with two iodine atoms in this manner.
Silver forms a cation with a charge of +1, represented as Ag+.
Barium metal forms the Ba²⁺ cation.
Cations are much smaller than their corresponding parent.
Rubidium will form cation: Rb+
Helium originated from suns, where the fusion of hydrogen atoms forms the helium.

You think to nuclear fusion.
Iron forms a cation.
The cation FeI2 does not exist on its own. Iron typically forms cations with a 2+ charge, like Fe2+, but it would not typically bond with two iodine atoms in this manner.
Cesium is a cation, meaning it is a positively charged ion. It forms the Cs+ cation when it loses an electron.
Silver forms a cation with a charge of +1, represented as Ag+.
The formula for the compound formed between aluminum and sulfur atoms is Al2S3. This is because aluminum typically forms a 3+ cation, while sulfur forms a 2- anion, resulting in a compound with a 2:3 ratio of aluminum to sulfur atoms.
Cesium is a cation, as it has a positive charge due to losing an electron.
No, NH3 is not a cation. NH3 is the chemical formula for ammonia, which is a neutral molecule composed of one nitrogen atom and three hydrogen atoms. Cations are ions with a positive charge due to losing electrons, while ammonia is not an ion.
Barium metal forms the Ba²⁺ cation.
