Detailed explanation-1: -Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite).

Detailed explanation-2: -Nonmetals are generally either gases or dull and brittle solids at room temperature. They are poor conductors of heat and electricity.

Detailed explanation-3: -Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids.

Detailed explanation-4: -Nonmetals are elements that generally cannot conduct electricity. They are the second largest class of elements after metals. Examples of nonmetals include hydrogen, carbon, chlorine, and helium. Properties of nonmetals include a relatively low boiling point, so many nonmetals are gases.

Detailed explanation-5: -Elements like O (oxygen) and H (hydrogen) are members of nonmetals. They can be a solid or a gas at room temperature. They have an appearance that is dull or without luster. Nonmetals are very poor conductors of heat or electric energy.
