Structure of Atom question

2024 · Q126

NEETChemistryStructure of AtomMCQ+4 / −1

The quantum numbers of four electrons are given below :

I. n=4;I=2;m1=−2;s=−12n=4 ; I=2 ; m_1=-2 ; s=-\frac{1}{2}n=4;I=2;m1​=−2;s=−21​

II. n=3;I=2;m1=1;s=+12n=3 ; I=2 ; m_1=1 ; s=+\frac{1}{2}n=3;I=2;m1​=1;s=+21​

III. n=4;I=1;m1=0;s=+12n=4 ; I=1 ; m_1=0 ; s=+\frac{1}{2}n=4;I=1;m1​=0;s=+21​

IV. n=3;I=1;m1=−1;s=+12n=3 ; I=1 ; m_1=-1 ; s=+\frac{1}{2}n=3;I=1;m1​=−1;s=+21​

The correct decreasing order of energy of these electrons is

  1. A
    IV >>> II >>> III >>> I
  2. B
    I >>> III >>> II >>> IV
  3. C
    III >>> I >>> II >>> IV
  4. D
    I >>> II >>> III >>> IV
