test unit 5

Question 1

electromagnitivity

Answer 1

the measure of the pull of an electron in a bonds

Question 2

LDF

Answer 2

Nonpolar
weakest forces
know drawing
two circle left side pos right side neg. squiggle in between is LDF
momentary shift in electron cloud that induces an electron shift in another

Question 3

DD

Answer 3

polar molecules
the closer the molecules are, the stronger the force
moderate melting point and BP

oval (left pos right neg inside) squiggle (DD) another oval cross arrows in between and then another oval underneath

Question 4

HB

Answer 4

strongest IMF
H and N, O, F

+ - + -
H – F squiggle (HB) H – F

Question 5

atoms strength

Answer 5

metals
ions
molecules (HB-DD-LDF)
noble gases

Question 6

ions

Answer 6

made of cations and anions (metals and nonmetals) held together by electrostatic attraction

Question 7

molecular compounds

Answer 7

made of nonmetals held together by shared electrions

Question 8

PICTURES
atomic

Answer 8

EVERY BOND IS BONDED TO EACHOTHER

Question 9

PICTURES
molecules

Answer 9

must have gaps different atoms

Question 10

ionic
PICTURES

Answer 10

no gaps but is bonded but not all bonded

Question 11

arrows on bonds mean what

Answer 11

show when bond is polar, the direction the electrons are being pulled to

Question 12

for noble gases what IMF is holding it together

Answer 12

LDF

Question 13

IMF

Answer 13

weak forces btwn molecules

Question 14

dipole

Answer 14

a polar bond or molecule whose ends have opposite chages

Question 15

more bonds means

Answer 15

takes longer to melt thus has a hugher BP and MP
