Structure of Atom

Shown below are portions of orbital diagrams representing the ground state electron configuration of certain elements. If ‘x’ of them violates Pauli exclusion principle and ‘y’ of them violates Hund’s Rule then what is ‘x’ multiplies ‘y’?

Out of the following, which is the correct match for radial probability of finding the electron of 2s orbital?

The maximum number of electrons with n = 3 and l = 3 is:

The longest wavelength of light that can be used for the ionization of lithium atom (Li) in its ground state is x × 108m. The value of x is_________. (Nearest Integer)

A proton and a Li³⁺ nucleus are accelerated by the same potential. If ${\lambda }_{Li}and{\lambda }_P$ <!-- [if gte mso 9]><xml> </xml><![endif]--> denote the de Brogle wavelength of Li³⁺ and proton respectively, then the value of $\frac{{\lambda }_{Li}}{{\lambda }_P}isx\times 10^{-1}.$ <!-- [if gte mso 9]><xml> </xml><![endif]--> The value of x is_________ (Rounded off to the nearest integer)           [Mass of Li³⁺ = 8.3 mass of proton]
