Atomic Theory, Bonding, and the Bohr Model
You cannot see atoms — but models let you predict how elements bond and what formulas mean.

Evidence you will build
- Bohr model diagram set (5 elements)
- Ion charge table
- Simple molecule formula worksheet
- Scientific development timeline
Why this matters
Molecular-level models underpin biotechnology and materials science — from medicines to new materials developed in Aotearoa.
What you will investigate and collect
You will represent atoms, ions, and simple molecules using the Bohr model and valence rules, then connect model history to how science builds knowledge. How electron arrangement explains bonding and how model accuracy improves with new evidence. Bohr diagrams, ion charge tables, molecular formula worksheets, and timeline notes on model development.
- Element symbol
- Proton count
- Electron arrangement (shells)
- Ion charge predicted

Isolate one fair-test comparison with a disposable small print
When one variable dominates your comparisons, printing a test shape keeps other factors steady.
