C2.2.1 - Metals/Non Metals

Question 1

Define metals

Answer 1

Elements that react to form positive ions (lose electrons)

Question 2

Define non metals

Answer 2

Elements that react to form negative ions (gain electrons)

Question 3

Physical properties of metals (6)

Answer 3

• Shiny
• Usually high melting/boiling point
• Solid (at room temp)
• Malleable
• Ductile
• Good conductors of heat/electricity

Question 4

Physical properties of non metals (6)

Answer 4

• Dull
• Usually low melting/boiling point
• Half are solid, half are gas (approx. At room temp)
• Brittle
• Non ductile
• Poor conductors of heat/electricity so insulators

Question 5

Chemical properties of metals (3)

Answer 5

• Lose electrons, form positive ions
• Don’t react with each other, but mix forming alloys
• Metal oxides dissolve in water forming “alkaline” solutions

Question 6

Chemical properties of non metals (3)

Answer 6

• Gain electrons, forming negative ions
• Non metals react with each other, forming compounds
• Non metal oxides dissolve in water forming “acidic” solutions
