Answer 7

covalent bond

Question 8

what is a polar molecule? how are electrons shared in polar covalent bonds?

Answer 8

A molecule where there is an unequal sharing of an electron pain, Larger atoms with larger nuclei will pull the electrons closer making the atom slightly negative while the smaller atom will be slightly positive.
