Y9 Metals and reactivity series revision

Lithium

Floats on water and fizzes without melting

Sodium

Melts into a ball on surface of water without flame

Potassium

Ignites on the surface of water with a lilac flame

Hydrogen

Diatomic gas produced when Gp 1 react with water

Zinc

More reactive than iron. Forms a 2+ ion

Aluminium

Forms a 3+ ion

Rubidium

More reactive than potassium

Silver ions

Displaced by copper metal

Copper

Doesn't react with acid

Hydrated iron (III) oxide

Chemical name for rust

Galvanising

coating in zinc (sacrificial protection against rust)

Reduction

Loss of oxygen OR gain of electrons

Oxidation

Gain of oxygen OR loss of electrons

Metal hydroxide

Alkaline product of metal reaction with water

Magnesium oxide

Formed when magnesium burns in air

Molten iron

Formed from the displacement reaction of aluminium with iron oxide (Thermite reaction)

OH- ions

Ions responsible for turning Universal Indicator purple (produced in reaction of alkali metals with water)

H+ ions

Ions present in all acids

Copper and magnesium sulfate

Products of displacement reaction between magnesium and copper sulfate

Lead and zinc nitrate

Products of displacement reaction between zinc and lead nitrate

Lead chloride and hydrogen

Products of reaction of lead with hydrochloric acid

Zinc nitrate and hydrogen

Products of reaction of zinc with nitric acid

Sodium hydroxide and hydrogen

Products of reaction of sodium with water

Sodium oxide

The dull substance formed when sodium tarnishes in air

Alkali metals

Name given to metals in Group 1

Sulfate

Has a 2- charge

Nitrate

Has a 1- charge

Displacement reaction

A reaction in which a more reactive metal displaces a less reactive metal from a compound of its ions.

Rusting

The term for when iron corrodes (reacts with oxygen and water)

Corroding

The term for when any metal reacts with oxygen and water

Gold

found in its native form (uncombined with other elements)
