l properties of metal:-#Reaction with oxygenMetals reacts with oxygen to FORM metal oxide.#Reaction with WATERWHEN metal react with water it FORMS metal hydroxide or oxide.#Reaction with DILUTE acidMetals reacts with diluted acid to form metals salt and hydrogen gas.#Reaction of metal with salt of other metalWhen metal reacts with salt sol. of other less reactive metal it displaces it from salt sol. and separate it out.#Reaction with hydrogenGenerally metals do not combines with hydrogen but FER more reactive metal like sodium , potassium , calcium and magnesium combines with hydrogen and forms metal hydride.Chemical properties of non metals:-#Reaction with oxygenNon metals reacts with oxygen to form non metallic oxide.#Reaction of non metal with waterThere is no reaction b/w non metals and water.#Reaction with dilute acideThere is non reaction b/w non metals and dilute acide.#Reaction of non metal with other non metallic saltDuring this reaction a more reactive non metal displaces less reactive non metal from its salt sol.#Reaction of non metal with chlorine Non metals reacts with chlorine to form non metallic chloride.#Reaction with hydrogen Non metal reacts with hydrogen to form non metallic hydrogen.
