Principles of Chemistry

Describe metallic bonding in electrostatic attractions

The electrostatic force of attraction between positive metal ions surrounded by a ‘‘sea’’ of delocalised electrons.

Draw a 2D Diagram describing a metal lattice

Explain why a metal is ductile/malleable

The atoms/ions are arranged in layers which can slide over each other when a force is applied.

Definition of malleable

This means they can be hammered into shape.

What is electrical current?

The flow of electrons.

Explain the electrical conductivity of a metal

There are delocalised electrons that are able to move and carry the charge through the structure.

How to calculate volume of gas?

Volume of gas = moles of gas x molar volume

How many moles of gas is there usually?

24,000 cm³ and 24 dm³
