What are two properties of most nonmetals? (1) high ionization energy and poor electrical conductivity(2) high ionization energy and good electrical conductivity(3) low ionization energy and poor electrical conductivity(4) low ionization energy and good electrical conductivity

The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1". In general it is known that nonmetals are very poor conductors of heat and electricity. The nonmetals that are solid are normally very brittle and has very little or no metallic luster at all. Nonmetals are highly reactive and show variety of chemical properties. It can also be pointed out that the nonmetals gain electrons very easily.

Although the diagram is not shown, i know that the convection is heated by a the core.
