# How many electrons does H_2SO_4 have? How many atoms does each element have?

Nov 28, 2016

Well, each hydrogen has one, and sulfur and oxygen each have 6 $\text{valence}$ electrons.

#### Explanation:

And in the Lewis structure of sulfuric acid, you can see where these electrons are distributed:

i.e. $H - O - S {\left(= O\right)}_{2} - O H$, else......

$H - O - {S}^{2 +} {\left(- O\right)}_{2} \text{^(-)} - O H$,

The chalcogen atoms each have 2 extra lone pairs of electrons around each centre, which accounts for the 6 electrons.
