If n=6 , the correct sequence for filling of electrons will be

If n=6n=6, the correct sequence for filling of electrons will be

Options

  1. Ans⟶(n−1)d⟶(n−2)f⟶npn s \longrightarrow(n-1) d \longrightarrow(n-2) f \longrightarrow n p
  2. Bns⟶(n−2)f⟶np⟶(n−1)dn s \longrightarrow(n-2) f \longrightarrow n p \longrightarrow(n-1) d
  3. Cns⟶np⟶(n−1)d⟶(n−2)fn s \longrightarrow n p \longrightarrow(n-1) d \longrightarrow(n-2) f
  4. Dns⟶(n−2)f⟶(n−1)d⟶npn s \longrightarrow(n-2) f \longrightarrow(n-1) d \longrightarrow n p

Correct answer

D. ns⟶(n−2)f⟶(n−1)d⟶npn s \longrightarrow(n-2) f \longrightarrow(n-1) d \longrightarrow n p

Step-by-step solution

6s→4f→5d→6p6 s \rightarrow 4 f \rightarrow 5 d \rightarrow 6 p for n=6n=6
