Frequently Asked Questions

What is the difference between metals and nonmetals?

Metals have one to three electrons in their outer shell, whereas non-metals have four to eight electrons. Another difference is that metals tend to lose their valence electrons, but non-metals share or gain valence electrons. Where metals form oxides which are basic, non-metals form oxides which are acidic.

What is the difference between metalloids and metals?

Metals have a metallic appearance and are good conductors of heat and electricity. Metalloids are usually capable of conducting, but even when they are, they do not conduct as well as metals. Metals are always malleable, while metalloids are usually, but not always, malleable.

What are the properties of metals and nonmetals?

The physical and chemical properties of the metals and nonmetals may be used to tell them apart. Metal Physical Properties: Lustrous (shiny) Good conductors of heat and electricity. High melting point. High density (heavy for their size) Malleable (can be hammered) Ductile (can be drawn into wires)
