Question

1pt metalloids are generally_________.

○ a. all solids, shiny, brittle, conductors, medium density
○ b. mostly gases, brittle, dull, low density, insulators
○ c. mostly solids, shiny, high density, conductors
○ d. mostly solids, dull, brittle, reactive, conductors

Explanation:

Metalloids are elements that have properties of both metals and non - metals. They are all solids at room temperature. They have a shiny appearance (lustrous), are brittle (not malleable or ductile), are semiconductors (a type of conductor with intermediate conductivity), and have medium density.

Answer:

A. all solids, shiny, brittle, conductors, medium density
