In the previous blogpost, we have discussed about the General Features of the Periodic Table.
Besides that, students taking GCE ‘O’ Levels / IGCSE / IB / IP examinations would also need to master the Common Properties of a Group.
Common Properties of a Group
Elements in the same group have similar properties:
- Same number of valence electrons
- Usually form ions with the same charge
- Form compounds with similar formulae
- Similar physical properties
- Similar chemical properties
In addition to the above, the following are observed as we go down a particular group:
- Proton number increases
- Number of electron shellls increases
- Relative atomic mass increases
Now, go ahead and try out some exam-based question and leave your suggested answers below.
