[S2] LESSON 33 : Atoms and Bonding EOY Revision Updates/Debrief

[S2 Maths + Science PMCians]

What we did in 2 hours:

This lesson, we started our Science EOY revision on Chemistry, covering the following topics:

1) Atoms and Molecules

 – We revisited the terms such as proton number, mass number, ions, isotopes, elements, compound and mixture, as well as recalled how to write electronic configurations of elements and the chemical formula of compounds.

2) Ionic and Covalent Bondings

 – We revised the properties of ionic and covalent compounds and how to draw the dot cross diagrams of these compounds.


What you received:

Do take time to attempt the Take Away Questions on Atoms and Bondings. The answers for the MCQs are provided in the workbook.


Special Mention:

Next lesson, we will continue with our Science EOY Revision on another Chemistry topic – Chemical Reactions


See you soon! 🙂
