GENERAL KNOWLEDGE

Detailed explanation-1: -The elements argon, krypton, and xenon are all non-metals. What property would these elements have in common Good conductor of thermal energy Poor conductor of electricity Shiny, lustrous surface Soft and malleable.

Detailed explanation-2: -Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Detailed explanation-3: -Nonmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids.

Detailed explanation-4: -Answer: The metals come with properties like high conductivity with low electronegativity, whereas non-metals have the opposite condition than metals. The metalloids have properties in the middle compared to metals and non-metals. Noble gases are elements that are present only in the form of gas.

Detailed explanation-5: -Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic lustre. Most nonmetals have the ability to gain electrons easily. They have a low melting point and boiling point.
