Answer to Question #127020 in General Chemistry for Rosé A

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.

II. Based upon the above information, solve the questions given below :

(a) Which of the following orbitals has the lowest energy?

   4d, 4f, 5s, 5p

(b) Which of the following orbitals has the highest energy?

   5p, 5d, 5f, 6s, 6p  

Answer 1

(a) The 5s orbital has the lowest energy.

(b) The 5f orbital has a high energy.
