why helium does not react with other elements to form compounds
helium has completely filled orbitals. hence it is chemically inert (or doesn't react with other elements).
You think probable to diatomic molecules but these are not formed by a reaction.
There are very many elements which will do that.
Elements dont react to form other elements. However, compounds can react with one another or decompose to form elements. More importantly, fluorine is a diatomic molecule, which means that it will never exist as "F" but always as F2.

Form an aqueous solution
YES!!!! Taking Sodium and Chlorine as an example. Sodium metal is an element. Chlorine gas is an element. Put them together in a gas jar and they will react to form the compound sodium chloride. In nature atmospheric nitrogen (an element) will react with atmospheric oxygen (also an element), when a lightning strike discharges, to form nitrogen oxides (compounds).

Cl, chlorine is an element, Cl2 is the molecular form of the element. When 'free' chlorine is so reactive that it will react with itself to form diatomic (2 atoms) molecules, but it is still an element.
This is the valence electron.
Being very reactive these elements react quickly and form compounds.
Metals react with acids to form H2. Metalloids also show this type of reactions.
Iron reacts with oxygen in air to for rust.
helium has completely filled orbitals and does not react with any element.

Ionic compounds are formed between metals and non-metals.
