Exploring Metals and Non-metals

What are three physical properties of metals?

• Brittleness

• Dull appearance

• High thermal conductivity

• High electrical conductivity, malleability, and luster.

How do metals generally conduct heat and electricity?

• Metals conduct heat and electricity through static charges.

• Metals use vibrations of atoms to transfer heat and electricity.

• Metals conduct heat and electricity through free-moving electrons.

• Metals rely on magnetic fields to conduct heat and electricity.

What is a common property of non-metals regarding their state at room temperature?

• Non-metals are always liquids at room temperature.

• Non-metals are often gases or solids at room temperature.

• Non-metals are primarily metals at room temperature.

• Non-metals are only found in solid form at room temperature.

Name two physical properties that distinguish non-metals from metals.

• Excellent conductivity

• Ductility

• Poor conductivity and brittleness.

• High malleability

Which metal is known for its malleability and ductility?

• Lead

• Copper

• Gold

• Iron

What is the reactivity trend of metals as you move down the periodic table?

• Reactivity of metals is highest at the top of the periodic table.

• Reactivity of metals increases down the periodic table.

• Reactivity of metals decreases down the periodic table.

• Reactivity of metals remains constant down the periodic table.

How do non-metals typically react with metals?

• Non-metals lose electrons to form positive ions.

• Non-metals react with metals by gaining electrons to form negative ions.

• Non-metals react with metals by sharing electrons.

• Non-metals do not react with metals at all.

What is the most reactive non-metal?

• Oxygen

• Nitrogen

• Chlorine

• Fluorine
