Question

The arrangement of orbitals on the basis of energy is based upon their (n+l ) value. Lower the

value of (n+l), lower is the energy. For orbitals having same values of (n+l), the orbital with

lower value of n will have lower energy.

8. Based upon the above information, arrange the following orbitals in the increasing order of

energy.

4s,

3s,

3p,

4d

9. Based upon the above information, Which of the following orbitals has the lowest energy?

4d,

4f,

5s,

5p

10. Which of the following orbitals has the highest energy?

5p,

5d,

5f,

6s,

​

Answer 1

Answer:

Lower the value of (n +l), lower is the energy . For orbitals having same value of (n +l), the orbital with lower value of n will have lower energy. ... Hence, 5s has the lowest energy. (b) 5p=5+1=6,5d=5+2=7,5f=5+3=8,6s=6+0=6,6p=6+1=7 Hence, 5f has highest energy. my dear please love
