Metals tend to form ions by:

• Gaining electrons

• Losing electrons

• Sharing electrons

• Neither gaining nor losing electrons

Nonmetals are more likely to form ions in reactions involving:

• Metalloids only

• Metals only

• Both metals and metalloids

• Neither metals nor metalloids

Which of the following is NOT a property of metalloids?

• Ability to conduct electricity better than nonmetals but worse than metals

• Shiny appearance like metals

• High malleability like metals

• Ability to act as semiconductors

The chemical reactivity of metals is primarily due to their:

• High melting points

• Ability to lose valence electrons easily

• Ability to gain electrons easily

• Low density
