Chapter 11, Problem 11A

Interpretation Introduction

Interpretation:The excited state of an atom needs to be explained.

Concept interpretation:When electron occupies higher energy orbit for temporary basis it is known as its excited state.

Answer to Problem 11A

Excited States refers to the level when an atom absorbs energy from external sources to go to the higher energy state. Electron can become excited when it is given an extra energy from external source that's why electron jumps from lower energy orbit to higher energy orbit. The energy absorbed by an electron could be in the form of small packets or Photon.

Explanation of Solution

The ground state describes the lowest possible energy that an atom can have and excited States refers to the level when an atom absorbs energy from external sources to go to the higher energy state. The energy absorbed by an electron could be in the form of small packets or photon and also by the collision from nearby atoms. It gives the electrons the sufficient energy to jump from lower to higher energy orbit.

Conclusion

So excited state configuration is basically a higher energy level arrangement. Atom occupiesthis excited state for a temporary basis.
