Answer 12

sharing, nonmetals

Question 13

equal sharing in covalent bonds means ____

unequal sharing means _____

Answer 13

nonpolar (do not have opposite ends), polar

Question 14

how do you indicate if a bond is ionic, polar, or nonpolar

Answer 14

ionic- >1.7
polar- .5-1.7
nonpolar- 0-.4

Question 15

explain AXE notation

Answer 15

A-central atom
X- atoms bonded to central atom
E- lone pairs on central atom only
example) PF5’s notation would be AX5

Question 16

of hybrid orbitals formed= what

Answer 16

of domains on the central atom

Question 17

what is bond polarity determined by

Answer 17

electronegativity difference in the bond (dipole)

Question 18

how is molecule polarity determined

Answer 18

whether the dipoles cancel or if there is a resultant

Question 19

what is the dipole?

Answer 19

electronegativity inbalance, represented by arrows drawn towards more electronegative element
where electrons are found within the bond

Question 20

has a magnitude
has a value
has a direction
ex) velocity

Answer 20

vector

Question 21

if dipoles cancel, you have a ______ bond

how do dipoles cancel

Answer 21

nonpolar

same magnitude, towards or away from each other

Question 22

how can you tell if a bond is polar

Answer 22

polar bonds have at least one of these two characteristics
one or more lone pairs on center atom (dipoles will angle)
if you have different atoms connected to your center (different electronegativities)

Question 23

Answer 23

planes
