Chemistry

Metals

What type of ions do metals form

Positive ions (Cations)

What are some properties of metals

Shiny

Sonorous

Good conductors of heat

Good conductors of electricity

High melting and boiling point

What is meant by reactivity of metals

How easily metals are able to lose their electrons to form positive ions by reacting with other substances

List the metal reactivity series

Potassium

Sodium

Lithium

Calcium

Magnesium

Carbon

Zinc

Iron

Hydrogen

Copper

How do u measure and compare the reactivity of a metals

Through comparing how metals react with either acid or water

What does a metal and acid form when reacting

Salt and hydrogen

How do u keep the metal reactivity experiment with acid fair

Use the same mass and surface area metal and also use the same concentration acid

What does a metal and water form when reacting

A metal hydroxide and hydrogen

What metals don’t react with water.

Zinc Iron and copper, magnesium does react but very little

Explain how displacement works

More reactive metals will displace less reactive metals from their compound

What is oxidation

Gain of oxygenW

What is reduction

Loss of oxygen

How is carbon useful in reduction

Carbon is more reactive than zinc iron and copper so it is able to therefore extract the metal from its compound (Reduction, loss of oxygen)
