Compare the physical properties of metals and non-metals in general with reference to malleability.

1. Both are malleable
2. None are malleable
3. only metals are malleable
4. only non-metals are malleable

Correct answer: only metals are malleable

Solution

Metals are generally malleable because their atoms can slide past one another without the structure breaking. Non-metals are usually brittle, so they do not show malleability in general.
