Metalloids are semiconductive.

Metalloids are solid.

Metalloids are brittle.

Which groups on the periodic table contain metalloids?

How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors?

They have one or two valence electrons, so they cannot lose electrons easily.

They have one or two valence electrons, so they can lose or gain electrons.

They have three to six valence electrons, so they cannot lose electrons easily.

They have three to six valence electrons, so they can lose or gain electrons.

The table shows columns that Brenda uses for her notes on the properties of elements. Her notes state that some elements can react to form basic compounds.Where should Brenda place this property in her table?

only in the column for metalloids

only in the column for nonmetals

in the columns for metalloids and for nonmetals

in the columns for metals and for metalloids

selenium (Se)

germanium (Ge)

phosphorus (P)

iodine (I)

Solar panels convert light energy from sunlight into electrical energy. What material is most likely used in solar panels, and why?

A nonmetal is used because it is a semiconductor and can become more conductive when more light shines on it.

A metalloid is used because it is a good conductor but can become less conductive when more light shines on it.

A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it.

A nonmetal is used because it is a poor conductor but can become more conductive when more light shines on it.

Based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (As) and antimony (Sb)?

Arsenic has a more metallic behavior than antimony because arsenic’s atoms have fewer electron shells.

Arsenic has a more metallic behavior than antimony because arsenic’s atoms have more electron shells.

Arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have more electron shells.

Arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have fewer electron shells.
