IC2.1.3 Ammonia 1 © Oxford University Press 2011 Ammonia gas exists as molecules. The atoms are held together by covalent bonds. Ammonia is a compound. The molecular formula of ammonia is NH 3. There are three atoms of hydrogen for every one atom of nitrogen.
IC2.1.3 Ammonia 1 © Oxford University Press 2011 When nitrogen and hydrogen react to form ammonia, the two types of atom join together by sharing pairs of electrons. Each shared pair of electrons is one covalent bond. By sharing electrons, both the nitrogen and hydrogen atoms achieve stable electronic structures.
