Question

19.Which of the following are all properties of nonmetals?

(A)usually donate electrons easily, typically brittle in the solid form, poor conductors of heat

(B)usually gain electrons easily, poor conductors of heat, poor conductors of electricity

(C)usually gain electrons easily, good conductors of heat and electricity


​

Answer 1

Answer:

A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity, and electronegativity. They gain or share electrons when they react with other elements and chemical compounds.
