It is about 100,000 times larger

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.
Polarity
The electron cloud has such a small mass because that's where all the electrons are! Electrons are fundamental particles having a mass of only 9.109 X 10-31 kg. To put that into perspective, a proton has a mass of over 1,800 times that of the electron.
It is generally envisioned that the atom consisting of a dense, small nuclues is made up of spherical protons and neutrons, yet this nucleus is surrounded by electrons constantly in rapid motion, orbiting the nucleus so frequently that it often covers a larger sphere around it. However, since the electrons are constantly moving, they hold no actual shape, so we call this area in which the electron orbits the nucleus the Electron Cloud. For modeling purposes, an atom is often displayed as a simple sphere with no complexions, but no one knows for sure exactly what these atoms look like upclose.
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.

The element krypton's atomic radius is 189 pm. This is a measurement of its atom sizes or the distance between the electron cloud and the nucleus.
The electron cloud. The atomic radius roughly describes the distance from the nucleus to the electron cloud.
nucleus is in the middle and the electron cloud is around it
I need to know also
Cloud...
Cloud...
The radius will decrease due to the positive charge of the nucleus drawing the electron cloud closer to itself
Electron in an atom is represented by electron cloud around the nucleus

The electron cloud in an atom is located outside of the nucleus.
