Say we have ammonia NH3 it has two lone pairs of electrons.
If a H+ hydrogen ion (proton) is added ammonia will become NH4+.
...
Does it get a positive charge because it basically gives up a electron in the bond it forms with H+.
usually in Covalent bonds an atom shares one electron but in this case Nitrogen would share 2 with H+
(kind of like a loss of 1 electron hence a positive charge?)
thanks!
been a while since I did chemistry.
Ammonium (NH
4+) has a positive charge because adding an additional proton makes the amount of protons and electrons in the molecule different. Ammonia (NH
3) has 8 electrons (each bond counts as 2 electrons) and 8 protons (3 from the hydrogens, and 5 from the nitrogen) and therefore the charge is 0. Ammonium (NH
4+) still has 8 electrons but now it has 9 protons, therefore its charge is 1+.
Also ammonia has 1 lone
pair.
