Question 8

ionic bond

Answer 8

attraction between oppositely charged ions that results in the transfer of electrons

Question 9

covalent bond

Answer 9

atoms share pairs of electrons equally

Question 10

polar covalent bond

Answer 10

unequal sharing of electrons results in a positive and negative end
