Question

Name three characteristics of metals and non-metals

Answer 1

Properties of metals:

• Good electrical conductors and heat conductors.
• Malleable - can be beaten into thin sheets.
• Ductile - can be stretched into wire.
• Possess metallic luster.
• Opaque as thin sheet.
• Solid at room temperature (except Hg)

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.
