Chapter 11, Problem 13A

Interpretation Introduction

Interpretation:

The study of electromagnetic radiation for understanding the arrangement of electrons in an atom is important, reason behind which is to be explained.

Concept introduction:

Due to the absorption or emission of electromagnetic radiation, the arrangement of electrons in an atom may change.

Answer to Problem 13A

The arrangement of electrons in each element is different which is responsible for the chemical properties of the element. The electrons are excited to higher energy level by the absorption of electromagnetic radiation but when it jump from higher energy level to lower energy level then it losestheir energy in the form of electromagnetic radiation.

Explanation of Solution

The electromagnetic radiation is responsible for the electrons’ arrangement because electrons generally occupy the lowest energy level in an atom. When they want to jump from lower energy level to higher level then they absorb the electromagnetic radiation and jump to higher energy level because different energy level of an atom have different amount of energy. Similarly, when the electrons jump from higher to lower energy level, then they emits the energy in the form of electromagnetic arrangement.Various changes in energy level require various frequencies of electromagnetic radiation.

Conclusion

Because of the absorption or emission of electromagnetic radiation, the arrangement of electrons in an atom may change.
