refers to a metal element placed in the block between Groups 2 and 3 in the periodic table.

a chemical that speeds up the rate of a reaction without itself being used up.

an atom or group of atoms with a positive or negative charge due to the loss or gain of electrons.

calculated by dividing the mass of a substance by its volume; a measurement of how tightly packed a substance's particles are per unit volume.

Transition metals

Chemistry

Corrosion and its prevention

Introduction to reversible chemical reactions

Chemical equilibrium

Industrial equilibria: Haber Process

Percentage yield and atom economy

Equilibrium: balance between rate, safety, environment and economics

Making ammonia

NPK fertilisers, agriculture and other applications

Comparing materials and their properties

In the Rates and energy changes unit, pupils learned about how energy changes are always involved in reaction, along with a range of methods for measuring and comparing rates of reaction using properties of reactants and/or products.

This unit covers corrosion, prevention methods, and properties of alloys, ceramics, polymers, and metals. It explores industrial processes like the Haber process, fertiliser production, reaction rates, yields, atom economy, and the trade-offs involving conditions and equilibrium.

Which of the following metals is a transition metal?

Transition metals have lower melting points.

Transition metals are generally stronger and harder.

Transition metals react more vigorously with water.

Which of the following is a characteristic of transition metals compared to Group 1 metals?

Transition metals can form ions with different {{}}, which leads to compounds with varying properties and colours.

It allows them to react with water vigorously.

It leads to compounds with varying properties and colours.

What is the significance of transition metals forming ions with different charges?

Which property is **not** typical of transition metals?

They can change the products of a reaction.

They speed up chemical reactions without being consumed.

Why are transition metals often used as catalysts?

The periodic table is organised into rows called periods and columns called {{}}.

Where are metals generally located on the periodic table?

An {{}} is formed when an atom gains or loses electrons.
