Frequently Asked Questions

Metals are elements that are generally hard, lustrous, malleable, ductile, good conductors of heat/electricity, and form positive ions.

Non-metals are brittle (if solid), non-lustrous, poor conductors, and form negative ions.

Property of metals to be beaten into thin sheets.

Property of metals to be drawn into wires.

Shiny appearance of metals due to reflection of light.

Due to presence of free electrons.

They lack free electrons.

Metals that produce ringing sound when struck.

Gold.

Because it reacts vigorously with air and water.

Metal oxides react with water to form basic hydroxides.

Their oxides form acids with water.

Gradual destruction of metals by air, moisture, or chemicals.

Iron reacts with oxygen and moisture to form rust.
