Electron Cloud
You think probable to ionosphere.
A cloud of electrons orbit an atom and its nucleus.
The place around the nucleus where an electron can be found is called the ORBITAL . Accordingly the place where the chances of finding an electron are the least is known as 'NODE' .
The region surrounding the nucleus in which electrons with certain energy move is called the orbital. It refers to a bit of space where there is a 95% chance of finding an electron.
The significance of the ninety percent contour is to determine the probability of finding the most electrons within a region.
I think the word you're looking for is "electron cloud". That term already describes where electrons are found. It would be kind of silly to define "electron cloud" in such a way that it describes an area where electrons are not found, wouldn't it?
You think probable to ionosphere.
The region of zero electron density is called a "node."

That depends on how it's drawn. It may give some idea of the probability of finding an electron in a given location, or it may just show the region of space where the electron is likely to be found. If it looks like a bunch of individual dots, the density of the dots gives some indication of the probability (the closer together the dots are in a region, the higher the probability of finding the electron in that region). If it looks like a solid object (or a collection of solid objects), it's just the region(s) where the probability is over some value.
The region around an atomic nucleus where an electron is likely to be moving.
The electron cloud. The atomic radius roughly describes the distance from the nucleus to the electron cloud.
Electron cloud on a+
None. You can use 80% or 95 or 99%. The reliability of your estimates will change in response.

The charge on electrons is equal to -1.6 X 10-19 C. According to Heisenberg's uncertainty principle, we cannot have the exact location of an electron, only we can have the region where the probability of finding an electron is high.
