What you practice
These are the CBSE Class 9 Structure of the Atom skills this quiz is built around.
- Compare Thomson, Rutherford and Bohr models.
- Distribute electrons and compute isotopes.
- Link valency to octet stability.
A useful tip
Valency is 8 minus valence electrons when they exceed 4: chlorine with 7 needs 1. The 8-minus rule predicts bonding capacity fast.
