Answer:
For the wavelenth of light spectrum, I believe the order would be red visible light, infrared, microwaves and radio waves.
Answer: Valence electron
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
The hydronium ions increase and the ph goes down.
The correct answer is:
The longest wavelength photon is n = 5 to n = 4.
The explanation:
According to he relation between the wavelength and energy, there have inverse relationship. The longest wavelength has the lowest energy.
and when:
-Transitions to n=1 are in the UV part of the spectrum and have the shortest wavelengths.
-and Transitions to n=2 are in the visible part of the spectrum and have wavelengths between 700nm and around 400 nm
-and Transitions to n=3 or greater are in the infra-red part of the spectrum and have the longest wavelengths.
- So the longest wavelength would correspond to the lowest energy and that would correspond to the difference in energy between n=5 and n=4
The activities that involves a chemist would be activities that involves quantification and qualification of a product. One that involves chemical reactions and the use of chemical substances. Hope this answers the question. Have a nice day.
