All the known elements are listed in the periodic table.

A chemist has a sample of an element. The chemist makes the following observations of the element:

- Solid - Malleable - Shiny - High electrical conductivity - High thermal conductivity - Gray color.

Which type of element could the chemist be studying?

• The element could be Ag because Ag is a metal.

• The element could be Sn because Sn is a metalloid.

• The element could be Ge because Ge is a metalloid.

• The element could be Ar because Ar is a nonmetal.
