What is Lewis structure for HgI2?

Answer 1

Not sure but this is what ive come up with. If you do your needs and haves you turn out with 4 bonds. xx xx I=Mg=I xx xx Since there is only two Valence electrons around the Mg atom, there must be two coordinate covalent bonds, one on each I. The x's represent the lone pairs.

Answer 2

..-----..

:I:Hg:I:

..-----.. there are four pairs of dots around each of the I's, and the Hg shares on pair with each I. The dashes I put in mean nothing, they are merely to keep the dots in their propper places, so disregard the dashes.

Answer 3

[Mg:S] (double bond)

Answer 4

H-Mg-H
