Here's my comparison between one aspect of meteorology and one of chemistry (of course, I learned the "chemistry" part in my biology class today).
PROTONS are a DEW POINT to the NEUTRONS' AIR TEMPERATURE; therefore, whether an atom is stable or not is like whether air is saturated or not.
A stable atom is like saturated (moist simply from water vapor, not liquid water) air, while an unstable atom is like unsaturated (dry) air.
"How so?" you may ask this way or someway else?
Pure and simple:
You can have a higher quantity of neutrons than of protons (meaning more neutrons than protons), but it can't work the other way around. Likewise, you can have a higher air temperature than a dew point, but the opposite is impossible.
Any more neutrons than protons, and the atom is unstable; similarly, any higher an air temperature than a dew point, and the relative humidity is less than 100%, thus, the air is unsaturated.
It is if you have the same number of neutrons as you have of protons that the atom is stable; likewise, if the air temperature is just as low as the dew point in a certain location, the air becomes saturated with water vapor.
It is, however, possible for unstable atoms and unsaturated air to become more stable and more saturated, respectively, and that's by decreasing the quantity of neutrons and the air temperature.
