### The equation

I know that the L in the equation means the # of electrons in a lone pair but what is a lone pair?

### Re: The equation

A lone pair refers to the dots surrounding the elements in a lewis structure. If it was shared, it would be represented by a line connecting the two elements. To find the number of lone pairs, simply count the number of dots.

Hi!
A lone pair of electrons refers to the electrons that are not involved in bonding when drawing the Lewis structures!

### Re: The equation

A lone pair would be the dots that aren't bonded but are still surrounding the element (those which don't have a line connecting to another element). The L in the formal charge equation would be the number of lone electrons for the element you are calculating it for.
