Helium does not form cation
Nuclear
cation
Iron is a metal, and is made of iron atoms. When it reacts to form a compound the iron atoms will lose electrons and become cations, either Fe2+ or Fe3+. All metals form cations when they form ionic compounds.
How Helium was MadeHelium is made in nature when two Hydrogen atoms, (also a gas) combine at the atomic level. This combination can take place when Hydrogen particles collide at great speed or under extreme pressure. Helium is the second most abundant substance in the observable universe. Hydrogen is the most abundant. Helium is already 'made' and its only form is a gas. It is a natural gas and on the Periodic Table of Elements.EmoLord777: Helium is also contained of 33.333% postitive atoms, 33.333% negitave atoms, and 33.333% neutral atoms.

Rubidium will form cation: Rb+
Helium originated from suns, where the fusion of hydrogen atoms forms the helium.
Nuclear
It forms a cation.
You think to nuclear fusion.
Iron forms a cation.
Bismuth forms a cation.
Cesium is an element that forms a cation.
A fusion of hydrogen atoms forms helium and formes a large amount of mass into energy.
NH3 is not a cation - it is polar but uncharged. however, when NH3 is dissolved in water, it forms NH4+ and OH-, and NH4 is a cation.

Do you mean "little"? The comparative and superlative forms are "littler" and "littlest," respectively, if you are talking about size (e.g. Lithium atoms are little, helium atoms are littler, and hydrogen atoms are the littlest). If you're talking about amount, then the forms are "less" and "least" (e.g. Alice has little money, Bob has less, and Charlie has the least).
