The smallest unit for measuring distance is the attometer. The attometer is equal to one 1,000,000,000,000,000,000th of a meter. This is the only unit small enough to provide some degree of precision when measuring distances on the atomic level - like the diameter of an atom's electron cloud.
The diameter of atoms is usually measured in Angstroms (1e-10 meters) or pico-meters (1e-12 meters). The former measurement unit yields numbers around one thus is favored by scientists who prefer numbers to be around this value (ease of computation I guess), the latter yields numbers in the 100's of pico-meteres.

The electron cloud.
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
Atoms are the basic building blocks of matter that make up everyday objects. A desk, the air, even you are made up of atoms. Adoms are in matter (matter is EVERYTHING).Answer:The space occupied by any atom is essentially empty, neither the proton or the electron takes up a lot of room. An electron has a diameter of 1 × 10-13 cm, about 1/1000 of the diameter of a proton. Photographs of atoms show a measurable shape but this is mostly the probability cloud where the electron might be. The protons take up about 1/100,000th of this volumeElectrons, protons and neutrons are composed of sub atomic particles.
The nucleus, consisting of protons and neutrons, is much more massive than the electrons.
Yes. They all have a central nucleus with an electron probability cloud surrounding it.

An atoms nucleus contains the proton and neutron while the electron cloud contains its electrons

The electron cloud.
The distribution of electron around an atom in various shells is sometimes referred to as electron cloud. If there are more electrons in certain space around the atom, that space is said to have a denser electron cloud.

The electron cloud.
In atoms. More specifically, they orbit the nucleus of an atom, in the aptly name electron cloud. Or electron shell.
Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
It is proton neutron in the nucleus and then electrons in the electron cloud.
Atoms with larger atomic numbers have a larger electron cloud, or system of orbitals
