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

Focus 1

Atomic Structure

Chemistry Paper 1 · All tiers

Full notes

Teach it

  • Atoms and Ions

    Atoms have a nucleus containing protons and neutrons.

Key facts

  • Atomic number = number of protons.
  • Mass number = protons + neutrons.

Key terms

Isotope: Atoms of the same element with different numbers of neutrons.
Ion: A charged particle formed by gaining or losing electrons.

Quick check

Explain why an atom becomes a positive ion.

Focus 2

Bonding Basics

Chemistry Paper 1 · All tiers

Full notes

Teach it

  • Ionic Bonding

    Metals lose electrons to form positive ions.

Key facts

  • Ionic compounds form giant lattices.
  • Ionic bonds are strong electrostatic attractions.

Key terms

Ionic bond: Electrostatic attraction between oppositely charged ions.
Lattice: Regular repeating structure in ionic solids.

Quick check

Why do ionic compounds have high melting points?

Focus 3

Cell Structure

Biology Paper 1 · All tiers

Full notes

Teach it

  • Animal vs Plant Cells

    Animal cells have a nucleus, cell membrane, cytoplasm, mitochondria, and ribosomes.

Key facts

  • The nucleus controls the cell activities and contains genetic material.
  • Mitochondria are the site of aerobic respiration.
  • Ribosomes are where protein synthesis happens.

Key terms

Organelle: A specialised structure within a cell that carries out a specific job.
Cell membrane: Controls movement of substances in and out of the cell.

Quick check

Explain why cells contain many mitochondria.
