Question

A student, took four metals $P, Q, R$ and $S$ and carried out different experiments to study the properties of metals. Some of the observations were: \All metals could not be cut with knife except metal $R$. \ Metal $P$ combined with oxygen to form an oxide $\mathrm{M}_{2} \mathrm{O}_{3}$ which reacted with both acids and bases. \Reaction with water :\ $P$ - Did not react either with cold or hot water but reacted with steam.\ Q- Reacted with hot water and the metal started floating.\ $R$ - Reacted violently with cold water.\ $S$ - Did not react with water at all.\ Based on the above observations answer the following.\ Metal which forms amphoteric oxides is\

(a) : It is given that metal $P$ combines with oxygen to form its oxide which reacts both with acids and bases, so oxide of $P$ is amphoteric in nature.\
