Least stable to most stable
(Or least electrons to most electrons)
The aluminium substances would retain the most heat for the longest period of time.
<h3>What is retaining heat?</h3>
Retaining of heat is the quantity of heat that a substance or medium can store over time or the amount of heat that a specific amount of that substance can hold in itself. Substances that store heat 'well' (for a long time) also require a long time to heat up.
Copper and aluminium have the highest thermal conductivity among the more common metals, whereas steel and bronze have the lowest. When determining the metal to utilise for a certain application, heat conductivity is a critical quality to consider.
In addition, potassium has the highest specific heat and the longest heat retention time. Polystyrene, a polymeric polymer, can retain heat for up to 11 hours. This implies it can hold heat for extended periods of time.
Hence the aluminium substances would retain the most heat for the longest period of time.

I think, the question should by:
When does quenching occur in a chemiluminescence reaction?
Quenching is a process that decreases the fluorescence intensity of any compound while chemiluminescence refers to emission of cold light due to a chemical reaction. Quenching of fluorophore occurs in a chemiluminescence reaction when the fluorescence of the fluorophore is quenched that leads to the decrease in the intensity of the fluorescence.
In terms of energy transfer, quenching occurs when loss of excitation energy of the molecule takes place in a chemiluminescence reaction.
Answer:
4.
A. Proton= Positive charge
B. Neutron= Neutral or no charge
C. Electron= Negative charge
5.
Protons and Neutrons are found in the nucleus.
Hope this helps!
