Solution
The correct option is D Non-metals are insulators
In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.
Physically, most nonmetals tend to be highly volatile (easily become a gas), have low elasticity, and are good insulators of heat and electricity. Chemically, they tend to have high ionization energy and electronegativity values, and gain or share electrons when they react with other elements or compounds.
17 elements are generally classified as nonmetals: -
Gases: hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon
Liquid: bromine
Solids: carbon, phosphorus, sulfur, selenium, and iodine
