Yes the paths make the atom easier to read than having to draw electrons all over the atom model
The term "orbital" was coined by Robert Mulliken in 1932.

Valency electrons are free electrons that are not attracted to other atoms. Valency electrons most often occur in a vacuum where they are not attracted to atoms (the reason thermionic devices are vacuumed) so yes, electron clouds can occur, very rarely in our atmosphere in the form of corona discharge from high voltage devices and more commonly in the vacuum of space as a glob of ionic turbulence
Not exactly. An electron is an actual physical particle with a negative charge. An electron cloud is (generally) a spherical area around the nucleus of an atom that predicts where the electrons might be located.
The particle not found in the nucleus is the electron
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?
Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.

Electrons are found in the shells and clouds.
Electrons are the particles found in electron clouds.
electrons are found in electron clouds.
i have no idea when it was discovered
electrons are found in the electron clouds while protons and neutrons are found in the nucleus
Electrons are found in electron clouds, which are ouside of the nucleus.
Neutrons and electrons are found in the nucleus of an atom; electrons are outside the nucleus in "electron clouds".
They are found in electron clouds around the nucleus.

Since electrons were particles, it was obvious that they had some mass.Ever since electrons were discovered, there was curiosity to find the magnitude of their charge and mass. Millikan performed the famous oil-drop experiment and found out the charge of electrons .After that he equated it with the charge to mass ratio of electron and found out the mas of the electron.
The question probably refers to 'the modern theory of electron clouds'. This theory is now almost a century old and is called quantum mechanics. It describes the states of electrons in an atom as 'electron clouds', so-called orbitals, which indicate the probability distribution of the electron wave function. In contrast to a naive classical picture that pictures electrons as point-like particles with given velocity and position, the quantum mechanical picture describes electrons as smeared-out matter waves following the Heisenberg uncertainty principle.
