Question 1

what happens with electrons in polar covalent bonds?

Answer 1

they a more attracted more to one side of the molecule

Question 2

what happens with electrons in nonpolar covalent bonds?

Answer 2

they are equally attracted to each side of the molecule

Question 3

what happens with electrons in ionic bonds?

Answer 3

they would permanently switch to one side of the molecule

Question 4

what’s the difference between polar and nonpolar covalent bonds?

Answer 4

in a polar covalent bond, the two atoms have different electronegativities, so the electrons spend more time on one side of the molecule, while in a nonpolar covalent bond, the two atoms have equal electronegativities, so the electrons spend an equal amount of time on each side of the molecule.

Question 5

what type of bond does lithium and fluorine form and why?

Answer 5

ionic bond, nonmetal and a metal, electronegativities are significantly different

Question 6

what type of bond does hydrogen and oxygen form and why?

Answer 6

polar covalent bond because the electronegativities are significantly different

Question 7

what type of bond does oxygen and oxygen form and why?

Answer 7

nonpolar covalent bond because they have the same electronegativity
