Electrons are found in the electron cloud that surrounds the nucleus.
the electron cloud
An electron cloud is a visual model of the most likely locations for electrons in an atom.
Electrons surround the nucleus of an atom in patterns called electron shells.
The electrons of an atom are located in the electron cloud.
It describes the most likely locations of electrons in atoms.
Electrons are the particles found in electron clouds.
energy levels
That would be the electron cloud. This is like the orbital model where there are electrons in each orbit level but the electron's location can not be predicted so it is said to be most likely at a point in the electron cloud.
The answer to that would be: An Electron Cloud Model
The electron cloud. An electron cloud is a volume or region in the atom where it is likely to find or detect an electron. It is actually really hard to detect an electron because an atom is mostly empty space, electrons are orbiting the nucleus at almost the speed of light so they orbit really fast, the electrons are very tiny and may be point like since we don't really know the volume or size of the electron, and an atom in reality is 3 dimensional which the electron cloud and orbitals is 3 dimensional. Since electrons are so hard to detect then they would call this volume or region of the atom an electron cloud because the electron cloud is a volume or region where they know that electrons are likely to be there even if they are hard to find. Or maybe the electron cloud is where they can also know the different sub- orbitals or subshells of the electrons.
Electrons are most likely to be found in the electron cloud surrounding the atomic nucleus.
