`Cl^(-)` has completely filled K and L shells. Explain.

Na^(+) has completely filled K and L shells. Explain?

Cl-has completely filled K, L & M shells. Explain it based on Bhor-Bury theory. (AS_(1))

Copper is regarded as transition metal, though it has completely filled 3d-orbitals. Explain.

(A) : Transition metals form colored ions (R): They have completely filled d-orbitals in the nth shell.

If a radioactive nucleus has a half life of one year, will be completely decayed after two year? Explain.

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):
