The first energy level in the electron cloud can hold a maximum of 2 electrons.

The dust cloud theory was first proposed by astronomers Fred Whipple and Jan Oort in the 1950s. They suggested that comets originate from a cloud of icy bodies located at the outer reaches of the solar system, now known as the Oort Cloud.
is the electron cloud
Its called the electron shell. Electrons will always fill up low orbitals first in the shell, an then as more energy is added to the atom, the electrons move up an orbit, then release the energy in some form, and they move back down to the lowest energy orbit.
The maximum number of electrons that can be found in the fourth energy level (ring) of an electron cloud is 32. This level can hold a total of 32 electrons in various sublevels, such as s, p, d, and f orbitals.
Your question is a bit vague, but if you are enquiring about the first electron shell in an atom, it holds a maximum of two electrons.

Robert A. Millikan was the first to determine the electrical charge of the electron.
Copernicus was the first to suggest it as part of a serious theory, in 1543.
The term "electron cloud" was coined by an American physicist named Richard Feynman. The electron cloud model is a visual representation of the possible locations of electrons in an atom. It is known that electrons are found on orbitals around the nucleus and this model visually allows us to picture the probable locations of the electrons around the nucleus.
