Question

what did you think by quantum number? what information is conveyed by
i) principal ii) Azimuthal iii) magnetic iv) spin quantum number

Answer 1

Principal quantum number (n) : It defines the main shell to which an electron belongs. The values of n =1,2,3,4,........

Azimuthal quantum number  : It tells us the number of subshells present in the main shell and the orbital to which an electron belongs. Its value is equal to 0 to (n-1)

Spin quatum number (s) : It tells us whether the electron in an orbital is spinning in upward direction or downward direction. s has two values +1/2 for upward spin and -1/2 for downward spin.

Magnetic quantum number (m) : It informs the level of degeneracy of the orbitals.

Answer 2

ii) Azimuthal .............
