A and B are elements with atomic numbers 16 and 17. Write different combinations of binary compounds known from them.

Answer»

Solution :Atomic number of `A = 16`. It is sulphur. Atomic number of `B = 17`. It is chlorine. Excess sulphur reacts with chlorine to give DIMERIC MONOCHLORIDE. Sulphur reacts with excess chlorine to give tetrachloride. Molten dimeric monochloride on saturation with chlorine GIVES dichloride. `2S+Cl_(2)rarr S_(2)Cl_(2),S+2Cl_(2)rarrSCl_(4) andS_(2)Cl_(2)+Cl_(2)rarr 2SCl_(2)`
