A spherical conducting shell of inner radius and outer radius has a charge q. A charge q is placed at the center of the shell. (a) what is the surface charge density on the (i) inner surface, (ii) outer surface of the shell? (b) write the expression for the electric field rice at a point x > from the center of the shell.

Down a group
As the electron enters a new shell, the distance between the nucleus and the outermost electron increases. Thus, atomic size increases down a group.
2. Along a period
As there is no new shell appearing along a period, the distance between the nucleus and the outermost electron remains same but due to attraction between the nucleus and the electron, the distance decreases. Thus, the atomic size decreases along a period.
But, an exceptional case is there of noble gases as they have larger atomic size as compared to the elements in that period because of negligible Van der Waals forces of attraction.
