  • Question 1/4
    4 / -1

    Which of the following quantum numbers are correct for last electron of Xe :-

    Solutions

    The last electron of Xe enters in 5p subshell. Therefore, n = 5, ℓ = 1

    Xe का अंतिम इलेक्ट्राॅन 5p उपकोश में जाता है इसलिए, n = 5, ℓ = 1

     

  • Question 2/4
    4 / -1

    For how many subshells the value of n+l can be 5?

    Solutions

    n + l = 5 for 5s, 4p, 3d

     

  • Question 3/4
    4 / -1

    How many total filled subshells are there in the inert gas of 5th period ?

    Solutions

    The inert gas is Xe.

    वह अक्रिय गैस Xe है

    ⇒ 1s  2s 2p 3s 3p 3d 4s 4p 4d 5s 5p

    ⇒ Total subshell = 11

    (कुल उपकोश)

     

  • Question 4/4
    4 / -1

    According to AuFbau principle which of the following sequence is correct :-

    Solutions

    3s         3p           3d           4p

    n + l     3+0=3    3+1 = 4   3+2=5     4+1=5
