📒copper is extracted from its ore by chemical and thermal reduction the metal is purified by electrolysis

🌟copper is reddish-brown extremely malleable metal which is good conductor of heat and electricity

🌟copper is not a reactive metal.in moist air the metal becomes covered with green coating of basic copper (ii) tetraoxosulphate VI and trioxocarbonate (iv)

🌟in aqueous solution the ions are extensively hydrated ,the hydrated copper(ii) ions are blue in colour

🌟Copper exhibit +1 and +2 oxidation state, the +2compounds are more stable

🌟Copper (I) ion undergo disproportionation in aqueous solution to give copper (ii) ion and metallic copper

🌟Copper is use in making electrical wires and ornamental objects , bronze and brass are important alloy of copper

🌟zinc ore are roasted in air and heated with coke to extract the metal which is purified by re distillation or electrolysis

🌟zinc does not possess many transition metal properties because it's 5d orbitals are completely filled when it exist as an ion!!

🌟zinc reacts with water to form zinc Oxide and basic zinc trioxocarbonate (iv) both of which form a continuous layer over the metal making it passive

🌟Zinc is amphoteric and react with both acid and base

🌟zinc is use for galvanizing iron and steel to prevent them from rusting

Learn the below alloy with all ur heart and soul and spirit for the sake of ur jamb score 🙏
