What this practice covers
These questions are drawn from past CIE 0620 Chemistry papers and filtered to metallic bonding. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on metallic bonding, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Describing metallic bonding as attraction between positive and negative ions. There are no negative ions in a metal.
- Saying metal atoms are held together by a sea of electrons. It is the ions, not atoms, that the electrons hold.
- Saying metals conduct because their ions move. The ions are fixed; the electrons move.
- Explaining malleability by saying the bonds break and re-form. The bonding is not broken, because the electrons move with the layers.
- Leaving the charges off a drawing of the metallic lattice.
- Forgetting that this whole subtopic is Extended and revising it in place of Core material.
