Focus topics (start here)

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

Focus 1

Atomic Structure & Radiation

Paper 1 · Both

Full notes

Teach it

  • Alpha, Beta, Gamma

    Alpha = helium nucleus.

  • Half-life

    Half-life is time for activity to halve.

Key facts

  • Alpha is most ionising, least penetrating.
  • Gamma is most penetrating.

Key terms

Half-life: Time for activity to halve.
Ionising: Removing electrons from atoms.

Quick check

A source has half-life 10 days. What fraction remains after 30 days?

Focus 2

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 3

Bioenergetics

Paper 1 · Both

Full notes

Teach it

  • Photosynthesis

    Photosynthesis uses light to convert carbon dioxide and water into glucose.

  • Respiration

    Aerobic respiration releases energy using oxygen.

Key facts

  • Chlorophyll absorbs light for photosynthesis.
  • Respiration happens in mitochondria.
  • Light intensity is the limiting factor at low light.
  • Anaerobic respiration in yeast produces ethanol and carbon dioxide.

Key terms

Aerobic: Reactions that use oxygen.
Anaerobic: Reactions that do not use oxygen.
Limiting factor: The factor that stops the rate increasing.

Quick check

Explain how temperature affects the rate of photosynthesis.
