If n = 5, the possible values of the angular-momentum quantum number I is: -4, -

Question

If n = 5, the possible values of the angular-momentum quantum number I is: -4, -3, -2, -1, 0 + 1, +2, +3, or + 4 For an electron in a given atom, the larger n, the larger the average distance from the nucleus and the higher the orbital energy. The preferred electron configuration of Molybdenum is [Kr] 5s^-1 4 d^5 rather than [Kr] 5s^2 4d^4. In the same period (n is the same), atomic radii of elements in group I are smaller than those of elements in the Group VII. The principal quantum number(n) can have integer values 1, 2, 3 and also relates to the average distance of the electron from the nucleus in a particular orbital. The effective nuclear charge, Z_eff is often substantially lower than the actual nuclear charge Z due to the electron shielding. The Heisenberg uncertainty principle state that it is possible to know precisely where an electron is and what path it follows. Quantum numbers I and m define three-dimensional shape of orbital and the spatial orientation of the orbital, respectively. Infrared light has higher frequency and hence higher energy than ultraviolet light. Chlorine has lower ionization energy (E_i1) and higher electron affinity (E_theta a) then Sulfur.

Explanation / Answer

Answer:

n=5 answer: True

Larger n value : True

Mo configuration :[Kr]5s14d5 True

Explanation: All orbitals are having the lone pair of electrons and it is the stable configuration.

Atomic radii: False

Explanation:

In the period from left to right the electrons can be filled in the same shell (n value is same). Hence the nuclear attraction increases on the outer most shell of the electrons then the atomic radii decreases.

The principle quantum number : True

Effective nuclear charge: True

Heisenberg uncertainity: True

Quantum nubers l and m : True

Ir and UV : False

Explanation: Uv frequency more and higher energy.

Cl and S: False

Explanation: Cl is the more electronegativity than Sulfur.
