The atomic number tells us the number of protons and electrons.
The atomic mass tells us the weight of the nucleus, which is the amount of protons and neutrons
Explanation:
Saturated solid/liquid solution is changed to an unsaturated solution by the dilution process.
When the saturated solution is diluted by addition large quantity of solvent it changed to an unsaturated solution.
Saturated solid/liquid solution can also be changed to an unsaturated solution by increasing the temperature or heating the solution.
A saturated solution is a solution where further solute will not dissolve in the solvent.
An unsaturated solution is a solution in which has the ability to dissolve more solute.
Answer:
the mass number is the number of protons and neutrons added and the average atomic mass is the weight of the protons and neutrons
