The charge on the tin ion is the same as the Roman numeral in the Stock name.

SnO₃ = tin(VI) oxide

Sn₂O₅ = tin(V) oxide

SnO₂ = tin(IV) oxide

Sn₂O₃ = tin(III) oxide

SnO = tin(II) oxide

Sn₂O = tin(I) oxide

Each oxide ion has a charge of -2.

To get the charge on a tin ion, you calculate the <em>total charge</em> on the O ions. Then you <em>change the sig</em>n and <em>divide by the number of Sn ions</em>.

E.g., for <em>Sn₂O₅</em>: Charge on 1 O = -2; charge on 5 O = -10; charge on 2 Sn = +10; charge on 1 Sn = +5.

It is really easy if you look up an electron configuration table (one that looks like a periodic table) and then just go down the rows left to right, top to bottom, and just stop when you get to where the element is on the table.

Which of the following is accurate in describing the placement and classification of iodine?
fenix001 [56]
You can answer this question by only searching the element in the periodic table.

The atomic number of iodine, I, is 53. It is placed in the column 17 (this is the Group) and row 5 (this is the Period).

The conclusion is that the iodine is located in Period 5, Group 17, and is classified as a nonmetal.
