After Bohr's discovery. In the 1900's.
An electron cloud is an atomic orbital.

It is impossible to know exactly where an electron is. Thus, the size of an electron cloud can be given only in terms of probability. Even then, the size of the electron cloud depends on how many electrons an atom possesses.
The electron cloud theory was developed in the late 1930s and early 1940s.
In modern quantum-based atomic theory, the space around the nucleus in which an electron moves is known as an electron cloud or orbital. This is a region of space where there is a high probability of finding the electron. The electron cloud is described by the probability density function of the electron's position in the atom.
Scientist use the electron cloud model to represent an atom.In the electron cloud model, an atom has two distinct regions-the nucleus and the electron cloud.
nucleus is in the middle and the electron cloud is around it
How do you draw and electron cloud for 2Br and for Br2
