Ionic Compounds (AQA GCSE Chemistry): Flashcards

Transfer of electrons from metal to non-metal

Charged particles formed by electron transfer

One electron transfers from Na outer shell to Cl outer shell

Positive sodium ion ($Na^+$)

Negative chloride ion ($Cl^-$)

Strong electrostatic attraction between opposite charges

Giant structure of ions in regular, repeating pattern

Electrostatic forces between oppositely charged ions

High melting and boiling points

Strong electrostatic forces need lots of energy to overcome

Higher charges create stronger forces of attraction

Cannot conduct electricity - ions in fixed positions

Can conduct electricity - ions free to move

Charged particles that are free to move
