The fairly positive hydrogen on one HF molecule will be attracted to one of these lone pairs on a nearby HF molecule. This is a hydrogen bond. Hydrogen bonds are attractions between a ฮด+ hydrogen on one molecule and a lone pair on a very electronegative atom (N, O or F) on another molecule.
Explanation:
Molten lead bromide
Explanation:
PbBr 2(l), is an electrolyte. During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms. Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.
