Explain how metalloids relate to metals and nonmetals.
a) metalloids exhibit properties of both metals and nonmetals.
b) metalloids display aspects of neither metals and nonmetals.
c) metalloids serve as a divider between metals and nonmetals.
d) metalloids demonstrate qualities of all metals and nonmetals.

A. Metalloids exhibit properties of both metals and nonmetals

Explanation: Metalloids are elements that has a metallic appearance such as shiny, dull amd ductile but they possess the properties of nonmetals in which they are intermediately poor conductors of heat and electricity in which they are good semiconductors.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
