Answer 19

metals

Question 20

all metals are ___ at room temperature. bonus: which element is the exception to this?

Answer 20

solid at room temp.
mercury (liquid at room temp)

Question 21

typical state of matter for most nonmetals at room temperature?

Answer 21

most nonmetals are gases; some are solid or liquid at room temperature

Question 22

T/F: most metals in solid form are brittle.

Answer 22

false: nonmetals in solid form are usually brittle and break easily

Question 23

which class of elements is a good conductor of heat/electricity?

Answer 23

metals

T/F: metals are malleable and ductile

Answer 25

true

Question 26

metals ___ electrons to form ___-ions

Answer 26

metals LOSE electrons to form CATIONS

Question 27

nonmetals ___ electrons to form ___-ions

Answer 27

nonmetals GAIN electrons to form ANIONS

Question 28

T/F: only nonmetals participate in ionic/metallic bonding

Answer 28

false: both metals and nonmetals participate in ionic/metallic bonding (since ions are made of metals+nonmetals!)

Question 29
