because I need answer the following questions.
The formal charge on the tin atom.
The formal oxidation number of the tin atom.
The overall charge of the molecular species shown.
If anyone knows how to do these questions..please show me a step by step solution..thank you.=)

Sn has a valence (charge) of +3, that is also its' oxidation number.
Sn had 3 valence electrons it lost so the next lowest level would have eight. Having lost the three electrons gave it a +3 charge.
Normally Sn has +4 or +2 as a oxidation number. It's charge in this molecule is +3 (an odd occurrence), I think it is written incorrectly, having never seen Sn as +3.
Cl has a charge of -1, it gained one electrons because it had 7 valence electrons, gaining the one gave it eight.
A compound must be neutral, so three Cl are needed to counter the one Sn.

Tin does NOT exist as a +3 ion. Only as a +2 or a +4 ion. Therefore, there must be a charge on this mythical "SnCl3" unit of which you speak.
