1.	An atom of an element has two shells with electrons . Thevalence shell has 2n+1electrons where nis the number of electrons in the inner shell . Thiselement can form a radical 'X' with hydrogen and two radicals Y and Z with oxygen, Z has more number of oxygen than Y. identifythe element and the radicals. write the reaction taking place between solutions of two salts , AgZ and XCl . Identify the type of reaction.
Answer» Solution :K shell can have only 2 electrons. That means n=2 and the number of electrons in L shell is 2n+1 which is equal to 5. The electronic arrangement that is 2,5 corresponds to nitrogen. Nitrogen can form `NH_(4)^(+)`with hydrogen. Y is `NO_(2)^(-)and Z" is " NO_(3)^(-)`. `AgNO_(3)+NH_(4)Cl toNH_(4)NO_(3)` This is a double DECOMPOSITION reaction where silver chloride being insoluble settles at the bottom. Therefore, this is a PRECIPITATION reaction.
