thats what i need help with

Answer 1

Ok so next time maybe add that it explains the number of covalent bonds in the atom because... (and then explain CaF2 tendencies in following the octet rule, like if it adds to 8 or isn’t completed yet.)

If this isn’t enough I would highly recommend asking your teacher after class even if they don’t like you or are one of THOSE teachers they gotta help you or it’s not fair for them to count you off points.
