Gold usually exists as a cation (some integer amount of positive charge) in solutions so it's a giver. It bonds covalently though, so it's also a sharer.
In theory 2 but in practice this has never been found. Helium is extremely stable and holds on to its electrons and does not share or "lend" them.
Yes, Non Metals Share Electrons to become stable, this is known as Covalent Bonding.

Magnesium is a metal element. There are 12 electrons in a single atom.
Only one valence electron.

Yes, you can give away or lend you Wii game to your friends.
Bromine borrows electrons

Nonmetal atoms are the atoms that borrow electrons. The number of atoms that can be borrowed or lent are what's known as valence.

Francium is an alkali metal that will lend electrons in an ionic compound.
Magnesium is a metal element. There are 12 electrons in a single atom.
Firstly I would like to correct you on your grammar. The question should in fact ask 'which' element gains 5 electrons. The question is also flawed form the start because more than one element gains 5 electrons. All elements in group 3 of the Periodic Table have 5 spaces in the outer shell. All elements want to feel complete, and the maximum amount of elements on the outer shell is 8. Therefore 3 + 5 = 8. So hey presto this is my answer to you. ~K :)
