Chemistry : Atoms and bonding


Students will build upon their work in the previous topic and study the history of the atomic model, how and why is has changed and evolved over the years. Pupils will then learn how to calculate relative atomic mass numbers using isotopic % abundance data. This topic also covers a recap of the key sections of The Periodic Table, types of bonding, and study of nanoparticles (their size, properties and applications).

The main SMSC/Personal Development content of this topic includes: PD15 – Sense of enjoyment and fascination in learning about themselves and the world around them, PD17 – Willingness to reflect on their experiences and PD20 – National assessments and examinations for indicators of pupil outcomes.

The main UN Rights of a Child covered are No.13 – Sharing thoughts freely and No.28 – Access to Education.
