Question

Which of the following elements is most likely to be attracted by a magnet.
(I) aluminum (ii) potassium (III) chromium

Also explain why?

Answer 1

Aluminum.

Aluminum is paramagnetic hence weakly attracted by the magnet compared to potassium and chromium.

A paramagnetic material have a generally weaker attraction to magnets and cannot retain their magnetic properties for long.

Chromium, unlike aluminum cannot be attracted by a magnet completely hence diamagnetic in nature.
