when it takes two lewis structures to accurately represent how an atomic diagram is

Question 16

formal charge

Answer 16

valence electrons - valence electrons owned by atom (non binding + 1/2 bonding

Question 17

what is known about the relation to formal charge and structure of atom

Answer 17

the correct structure will have lowest formal charge

Question 18

polar covalent 2

Question 22

In vspr what counts towards shape of atom

Answer 22

every single electron connection, even lone pairs count as 1

Question 23

do lone pairs affect electron angles

Answer 23

they do because they’re slightly bigger

Question 24

molecular geometry

Answer 24

bonds that are actually formed not including loan pair
