Question

Write the values of four quantum numbers for 3d electrons

Answer 1

The values of the four quantum numbers are n=3,l=2,m=+2 to -2 and s=+1/2 or -1/2.

• n is called the principal quantum number and for 3d orbital n is equal to 3.
• l is called the azimuthal quantum number and for d orbital, it is equal to 2.
• m is called the magnetic quantum number and its value is given as +l to -l. Thus its value is +2 to -2.
• s is called the spin quantum number and its value is +1/2 or -1/2.
