Focus topics (start here)

Each card is a full micro-lesson: learn → check → apply.

Focus 1

Atomic Structure and Periodic Table

Paper 1 · Both

Full notes

Teach it

  • Atoms and Isotopes

    Atoms have protons, neutrons, and electrons.

  • Electron Configuration

    Electrons fill shells 2,8,8 for first 20 elements.

Key facts

  • Period number = number of electron shells.
  • Group 0 elements are noble gases and are unreactive.

Key terms

Atomic number: Number of protons in the nucleus.
Mass number: Number of protons plus neutrons.
Isotope: Same element with different numbers of neutrons.

Quick check

An atom has mass number 23 and atomic number 11. How many neutrons?

Focus 2

Bonding, Structure, and Properties

Paper 1 · Both

Full notes

Teach it

  • Ionic Bonding

    Metals lose electrons; non-metals gain electrons.

  • Covalent Bonding

    Non-metals share electrons.

Key facts

  • Graphite conducts because of delocalised electrons.
  • Diamond is hard due to a giant covalent lattice.

Key terms

Ionic bond: Electrostatic attraction between oppositely charged ions.
Covalent bond: A shared pair of electrons between atoms.
Metallic bond: Attraction between positive ions and delocalised electrons.

Quick check

Explain why metals conduct electricity.

Full notes

Teach it

  • Gas Tests

    Hydrogen: squeaky pop.

  • Ion Tests

    Carbonates release CO2 with acid.

Key facts

  • Flame tests: Na yellow, K lilac, Cu green.
  • Pure substances have fixed melting and boiling points.

Key terms

Precipitate: An insoluble solid formed in a reaction.
Chromatography: Technique for separating mixtures.

Quick check
