inc. going up

inc. from left to right

19
Q

bond polarity

A

measure of inequality in e- sharing btwn 2 bonded atoms

20

= electroneg. (e- shared) on atoms of a bond

21
Q

polar cov. bond

A

unequal electroneg. (e- shared) on atoms of a bond

22
Q

polarity-ionic relationship

A

polarity inc. –> bond more ionic
