Which element has (a) two shells, both of which are completely filled with electrons ? (b) the electronic congiguration 2, 8, 2 ? (c) a total of three shells, with four electrons in its valence shell ? (d) a total of two shells, with three electrons in its valence shell ? (e) twice as many electrons in its seconds shell as in its first shell ?

In an atom the number electrons in M-shell is equal to the number of electrons in the K and L shell. Answer the following questions. (AS1) Which is the outer most shell?

The K, L and M shells of an atom are full. Its atomic number is ________.

A spherical shell of copper is completely filled with a liquid at a temperature t^(@)C . The bulk moduls of the liquid is K and coefficient of volume expansion is gamma . If the temperature of the liquid and the shell is increased by DeltaT , then the outward pressure Deltap on the shell that results from the temperature increase is given by ( alpha is the coefficient of linear expansion of the material to the shell):

The cell , Zn//Zn^(2+) (1M) // Cu^(2+) (1M) // Cu (E_("Cell")^@ = 1.10V) , was allowed to be completely discharged at 298 K. The relative concentration of Zn^(2+) to Cu^(2+) is
