Question

The (n+l) value for 4f-subshell

Answer 1

Answer:

7

Explanation:

The principal quantum number and azimuthal quantum number of 4f subshell are 4 and 3.

Therefore n+l=4+3=7

Answer 2

Answer:

14

Explanation:

The electron gift withinside the atom may be defined via way of means of 4 units of quantum variety, Principal quantum variety that's denoted via way of means of n (Possible fee are 1, 2, 3, 4,….), Azimuthal quantum variety that's denoted via way of means of l (feasible values are 0, 1, 2, 3,….,(n-1), magnetic quantum variety that's denoted via way of means of ml (feasible values-l,…….,-1,0,1,…..,+l and spin quantum variety that's denoted via way of means of ms(feasible values +1/2, -1/2.

For a 4f orbital, the main quantum variety is n = 4, the azimuthal quantum variety is 3. The values of magnetic quantum numbers will be -3, -2, -1, 0, +1, +2, +3.

Total 7 orbitals are found in 4f subshell. Each orbital can comprise  electrons which can be found in contrary directions. So a complete 14 electrons are found in a 4f orbital.

Note:

The azimuthal quantum variety is likewise called angular momentum quantum variety or orbital quantum variety. It describes the subshell and determines the importance of the azimuthal quantum variety.
