The movement of an electron from a higher energy level to a lower energy level in an atom, a photon is emitted.

<h3>What is photon?</h3>

Photon can be defined as those particles in a quantum of light. It is also defined as a particle of light.

However, Photons are usually emitted or released when electrons moved from a higher energy level to a lower energy level.

<h3>What is an atom?</h3>

An atom is the smallest particles of an element which can take part in a chemical reaction.

  • Some substances are monoatomic consisting of only one atom

  • Some are diatomic consisting of two atoms, Example: Oxygen atoms ( O2 ), Hydrogen atoms ( H2 )

  • Some atoms such as Ozone ( O3 ) are triatomic consisting of three atoms.

  • Some are polyatomic

During a spectrophotometric analysis of an unknown, you measure your solution's absorbance, and the value is higher than the hig
Reil [10]

Answer:

A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can be calculated if the dilution process is recorded. Beer's law only applies to dilute solutions, so diluting the unknown is better than making new standards.

Explanation:

Beer's law states that <em>absorbance is proportional to the concentrations of the absorbing species</em>. This is verified in the case of diluted solutions (0≤0.01 M) of most substances. <u>As a solution gets more concentrated, solute molecules interact between themselves because of their proximity. </u>When a molecule interacts with another, the change in their electric properties (including absorbance) is probable. That's why <u>the plot of absorbance versus concentration stops being a straight line</u>, and <u>Beer's law is no longer valid.</u>

Therefore, if the absorbance value is higher than the highest standard,  dilutions should be made. Once this concentration is determined, the full strength concentration can be calculated with the inverse of the dilution.
