Which atom gets extra lone pair

How do you know which atom gets the extra lone pair in a molecule, if they are both below n=3?

Are you referring to Lewis Structures? If so, I think it is whichever one is more electronegative as long as you apply the valence electron and octet rule correctly.

You have to look at the formal charges. Generally we try to keep the central atom at a zero FC and the outer atoms can have negative charge if necessary.
