1.	Write down the outermost electronc configuration of alkali metals. How will you justify their placement in group 1 of the periodic table?
Answer» Solution :All the ELMENTS of GROUP (A) or I, i.e. Alkali metals have the similar outer electronic configuration, i.e., `ns^(1)` where n refers to the NUMBER of principle SHELL. These electronic configuration are given below. Hence, placement of all the elements in group 1 of the periodic table because of similarity in electronic configuration and all the elements have similar properties.
