N level Sci Chem - Metals
Howdy!
I'm feeling driven to get the Loom videos ready so I could journey with you towards your national examination.
I hope you have been good.
Today resource on metals and there are a total of 31 MCQ questions for the last ten years. If you do a quick math, that is an average of 3 metal-related MCQ per year.
This year, there could be more because the one full section on Organic Chemistry has been removed from your testable syllabus. More information on Syllabus 5106 Year 2020
A summary of this chapter popular question includes:

A summary of this chapter popular question includes:
- Structure of alloys
- General properties of metals (take note: Group I metals - Alkali metals do not behave like conventional metals)
- Advantages of recycling
- Conditions for rusting, especially how oxygen gas is used up and water level in a set-up will rise accordingly)
- Reactivity of metals (based on observation of reactions, with water, with steam, with carbon)
- Blast Furnace
A breakdown on the weightage of this chapter in 2019 examination paper:
- Paper 3 - 20 % (That's 4 out of 20 questions)
- Paper 4 - 13.2% (That's about 5 marks, testing on reactivity series of metals)
So before you watch the following videos, take a good moment to familiarise yourself on the Reactivity Series.
