Answer 14

increases

Question 15

electro.neg. down a group

Answer 15

decreases

Question 16

resonance

Answer 16

all bonds are equivalent in length and energy. (double bonds can be on any side)

Question 17

Answer 17

when cation and anion bond creating a rigid well defined 3 dimensional arrangement

Question 18

cations

Answer 18

metals

Question 19

anions

Answer 19

nonmetals

Question 20

covalent bond

Answer 20

formed by 2 atoms by sharing one or more pairs of e-

Question 21

polar

Answer 21

one atom exerts a greater attraction for the bonding electrons than the other

Question 22

nonpolar

Answer 22

electrons shared eqully

Question 23

double and triple bonds

Answer 23

as # of bonds increase, bond strength increases, length decreases

Question 24

INTRAmolecular bonding

Answer 24

bonds between atoms or ions that create new compounds. e- are transfered or shared between atoms
