Chapter 11, Problem 10A

Interpretation Introduction

Interpretation: Among Li ion and Cu ion, which emits higher energy photons needs to be identified.

Concept interpretation:Photons are small discrete packets of energy. No charge and they travel at the speed of light.

Answer to Problem 10A

Copper ions emit higher energy photons than Lithium ions.

Explanation of Solution

Photons of copper ions have higher energy than Lithium ions because copper ions have shorter wavelength and have higher energy, whereas Lithium ion emit longer wavelength photons and have lower energy.

Conclusion

The atom emits shorter wavelength ions have higher energy and those atom that emits longer wavelength has lower energy.
