Question

An electron designated by quantum number n=4, l=2, m=0 occupied which orbital
​

Answer 1

It occupied a 4d orbital.

• In an electronic configuration 'n' is called the principal quantum number.
• The term 'l' is called an azimuthal quantum number.
• 'm' is called a magnetic quantum number.
• For l=2 the orbital is d.
• For n=4 the orbital form is 4d.
• Again for l=2, the value of m is +2 to -2.
• Thus it gives a total of five 4d orbitals.
• Thus the orbital is 4d.
