um so i need some help for chemistry as my teacher is away all week. PLEASE if you can help me as i also have a test on thursday.
who can explain electron shells to me?
also ions and the ionic compound forming method?
and is the ion for ammonia NH4 r NH3
(the 4 and 3 being little under the H)
thank you.

The whole business of electron shells is too big to explain here but should be accessible in any basic textbook or you could Google it - though I couldn't find anything suitable.
Bubble ammonia (NH3) through water (H2O) and you'll get some ammonium hydroxide - that is, two ions, ammonium and hydroxyl, though the latter will have a water molecule bonded to make it a hydroxonium ion (H3O+)
NH3 + H2O → NH4+ + OH-

That reaction goes in the oposite direction. Ammonium hydroxide has no real existence; it would instantly decompose to ammonia and water.
Ammonia is NH3
The ammonium ion is NH4+
