Electrons can not be located in one specific place, but are sort of "spread" over their orbit. When doing an experiment to find their location, there is a certain probability of finding it within a certain unit of volume. The word "cloud" is supposed to conjure an image of this behavior of the electron.
The region of an atom in which the electrons move is called the electron shell, or electron cloud.
The electrons occupy the electron cloud. It is not a cloud at all; it is simply a region where electrons are most likely to be found.
Electrons surround the nucleus of an atom in patterns called electron shells.
If you are talking about elements, they are electrons.
Atomic size is defined as the distance between the nucleus and the outermost electron in an atom. Since electrons occupy regions of space called orbitals, which have fuzzy boundaries, it is difficult to pinpoint an exact boundary of an atom. Additionally, the electron cloud distribution is not uniform, making the atomic size less precise.

Electron cloud or also called electron orbitals.

The region around the nucleus where the electrons are located is called the electron cloud or electron shell. Electrons exist in specific energy levels within these shells, determined by their distance from the nucleus.
The electrons of an atom are located in the electron cloud.

The electrons in an atom are located in what is called the electron cloud. The electron cloud is an "area of probability" where electrons may be. The electrons actually occupy fixed energy levels, the so-called Fermi energy levels, around the nucleus of the atom, and we identify these energy levels as shells and orbitals.

The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
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.
Argon has 18 electrons in its electron cloud.
