How many electrons in an atom with atomic number 105 can have (n + l) = 8 ?

Question

How many electrons in an atom with atomic number 105 can have (n + l) = 8 ? (A) 30 (B) 17 (C) 15 (D) Unpredictable

Tardigrade Admin · Accepted Answer

Write the configuration of 105 and find out electrons with n + l = 8. There are 14 electrons in 5f-orbitaIs (5 + 3 = 8) and 3 electrons in 6d-orbitals (6+2 = 8 ) making total = 17.

Write the configuration of $105$ and find out electrons with $n + l = 8$ .
There are $14$ electrons in $5 f$ -orbitaIs $(5 + 3 = 8)$ and $3$ electrons in $6 d$ -orbitals $(6 + 2 = 8)$ making total $= 17$ .
