Question

Youare given twosolid one ofwhich is ametallic elements and othera nonmetallic element.write downfiveproperties which can be used todistinguish

Answer 1

Answer:

Physical properties of metallic character:

metallic luster, shiny appearance, high density, high thermal conductivity, and high electrical conductivity.

Physical properties of nonmetallic character:

high ionization energies and electronegativities, generally poor conductors of heat and electricity, generally brittle, with little or no metallic luster, and have the ability to gain electrons easily.

Explanation:

Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
