Year 10 Chemistry Lesson Pack – Atomic Structure

Introduce atomic structure with this complete lesson pack: PowerPoint, atomic structure calculations, diagram drawing task, and exit ticket worksheet.

This resource is designed for WJEC GCSE Chemistry Unit 1 (Triple Award, Year 10) but can be adapted for any GCSE science course. It introduces the basic structure of the atom and ensures students can calculate numbers of protons, neutrons, and electrons from atomic and mass numbers.

Lesson Content Covers:

Structure of the atom: nucleus, protons, neutrons, and electrons.

Relative masses and charges of subatomic particles.

Atomic number and mass number definitions.

Calculating protons, neutrons, and electrons.

Why atoms are neutral.

What’s Included:

PowerPoint presentation (.pptx) – objectives, starter questions, worked examples, practice problems, plenary, and homework.

Atomic Structure Calculations Worksheet (.pdf) – fill-in tables for protons, neutrons, electrons.

Atom Diagram Drawing Task Worksheet (.pdf) – draw labelled diagrams for hydrogen, carbon, lithium, sodium.

Exit Ticket Worksheet (.pdf) – quick 3-question plenary check.

How it can be used:

As a complete 60-minute lesson.

To introduce atomic structure in GCSE Chemistry (WJEC/Edexcel/AQA/other boards).

For revision and recap of atomic basics before bonding topics.

Adaptable for homework or cover lessons.
