AQA GCSE Chemistry - Atomic Structure and the Periodic Table: Properties of Transition Metals

This set of flashcards covers key vocabulary and concepts related to the properties of transition metals as outlined in the AQA GCSE Chemistry curriculum.

Transition Elements

Elements that are harder, stronger, and have higher melting points compared to group 1 elements.

Comparison with Group 1

Transition metals are much less reactive and do not react as vigorously with oxygen or water.

Typical properties of transition metals

They have ions with many different charges, form coloured compounds, and are useful as catalysts.

Chromium

A transition metal known for its +2, +3, +4, +5, and +6 oxidation states.

Iron

A transition metal that can have oxidation states +2, +3, +4, +5, and +6.

Cobalt

A transition metal that has ion charges of +2, +3, +4, +5.

Nickel

A transition metal with common oxidation states of +1, +2, and +3.

Copper

A transition metal known for its +1, +2, +3, +4, and +5 oxidation states.

Catalyst

A substance that increases the rate of a chemical reaction without being consumed.

Decomposition of hydrogen peroxide

A process catalyzed by transition metals to produce water and oxygen (2H2O2 -> 2H2O + O2).

Haber Process

A chemical reaction used for the production of ammonia (N2 + 3H2 ↔ 2NH3) involving transition metals.

Manufacture of Margarine

A process where hydrogen is added to double bonds in fatty acids, facilitated by transition metals.

Lustrous

A property of metals characterized by a shiny appearance.

Ductile

A property of metals that allows them to be drawn into thin wires.

Malleable

A property of metals that allows them to be hammered or pressed into shape without breaking.
