# How would you express Tin (IV) oxide as a chemical formula?

Mar 4, 2017

$S n {O}_{2}$

#### Explanation:

We know oxides are compounds made of a metal, and oxygen.

Oxygen always has a $- 2$ charge in these compounds, and since this compound has a metal with $+ 4$ charge, it takes two oxygens to balance the charge of one metal atom.

The symbol for tin is $S n$ (after its latin name, Stannum), so we just put them together:

$S n {O}_{2}$
