why is there a dative bond in ammonia? can't it just be a lone pair and how does it give 2 electrons to hydrogen when hydrogen already has 1 electron, wont it make hydrogen have 3 electrons, i thought this wasn''t allowed?

ammonia does not have a dative covalent bond, it has 3 covalent bonds and 1 lone pair. It is the presence of the lone pair that allows ammonia to make a dative covalent bond.

Ammonia will form a dative bond with a hydrogen ion, H+ this has no electrons. It will not form a dative bond with a hydrogen atom.

have a look here, it may help a bit
