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. (i) All metals could not be cut with knife except metal R. (ii) Metal P combined with oxygen to form an oxide M2O3 which reached with both acids and bases. (iii) 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
