Metals 1

Metals are solids at room temperature MOST likely because

• they have high melting and boiling points

• they are malleable and ductile

• they are hard and dense

• they have mobile electrons

Metals are always reducing agents when they react because

• they cause the other reactant to decrease in size

• they cause the other reactant to increase in size

• they donate electrons to the other reactant

• they receive electrons from the other reactant

Metals always react with non-metals to form IONIC compounds

• True

• False

Ag does NOT react with acids because

• Ag is unreactive

• Ag is lower than H in the reactivity series

• Ag is higher in the series than H

Al is higher in the reactivity series than Ca

• True

• False

The position of an element in the reactivity series is determined by how reactive it is.

• True

• False

A more reactive metal will be able to displace a less reactive metal from its compound.

• True

• False

Select the acid from the list below.

• H20

• H2CO3

• OH

• NaOH

All acids contain H

• True

• False

Metal oxide + acid ->

• salt

• water

• carbon dioxide

• hydrogen gas
