What Is The Difference Between Metals,non-metals, And Metalloids?

Metals are the chemical elements which have the ability to lose electrons to form positive ions. They form metallic bond with metals and ionic bond with non-metals. In metallic bond positive ions are surrounded by electrons and no electron is present in the outer most shell of an atom in metallic bond. Metals are good conductors of heat and electricity. They are shiny, malleable and ductile.

Non-metals are poor conductor of heat and electricity. They are dull, brittle and unmalleable. They have high electronegative and has the ability to gain electrons to form negative ions.

Metalloids are intermediate between metals and nonmetals. They have both the properties of metals and non-metals. They behave as semiconductors and are unmalleable.
