Question

In nature, aluminium is found in the form of compounds while gold is found in free state. Give reason.

Answer 1

This is because of the relative positions of the metals in the activity series. Aluminium is a reactive metal as it is placed above hydrogen in the activity series. It react vigorously and exists in combined form. Gold is placed much below hydrogen in the series. It is very less reactive and do not form compoounds easily, hence it occurs in the free state.
