1.	An element M has atomic number 12. (i) Write the electronic configuration and valency. (ii) Is M a metal or non-metal ? Give reason in support of your answer. (iii) Write the formula and nature (acidic/basic) of the oxide of M.
Answer» Solution :(i) Electronic configuration of M `K=2, L=4` VALENCY = 4 (ii) M is a non-metal because it cannot LOSE the ELECTRONS easily. (III) `CO_(2)`. It is ACIDIC in nature. Oxides of non-metals are acidic in nature.
