in 1926
In the early 1900's. See Wikipedia entries for JJ Thomson and Ernest Rutherford.
The concept of the electron cloud was developed by Erwin Schrödinger in 1926 as part of his wave mechanics theory. Schrödinger's work built upon previous discoveries in quantum theory made by scientists such as Max Planck, Albert Einstein, and Niels Bohr.
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.
Electron in an atom is represented by electron cloud around the nucleus
No, the electron cloud is not heavy. An electron weighs approximately 2000 times less than a proton or a neutron, so almost all the weight of an atom lies in the nucleus, not in the electron cloud.
Germanium has 32 electrons in its electron cloud.
After Bohr's discovery. In the 1900's.
i have no idea when it was discovered
an atom
Rutherford.
he discovered it in 1937
Nobody "invented" the electron cloud. The concept was discovered by Werner Heisenberg in 1926.
The concept of the electron cloud was developed by Erwin Schrödinger in 1926 as part of his wave mechanics theory. Schrödinger's work built upon previous discoveries in quantum theory made by scientists such as Max Planck, Albert Einstein, and Niels Bohr.

The dust cloud theory, which suggests that the solar system formed from a rotating disk of gas and dust, was proposed by Russian astrophysicist Viktor Safronov in the 1960s. He published his ideas in his book "Evolution of the Protoplanetary Cloud and Formation of the Earth and Planets."
The electron cloud theory was developed in the late 1930s and early 1940s.
An electron cloud is an atomic orbital.
