The smallest atom is helium (nucleus and electrons) while francium is the largest.
Helium: 28 picometer
francium: 260 picometer
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
5e-8cm
The nucleus of the atom has a diameter of about meter, whereas the atomic diameter is about meter. This means that the nucleus has a diameter 10,000 times smaller than the atom. The nucleus of the atom has a diameter of about meter, whereas the atomic diameter is about meter. This means that the nucleus has a diameter 10,000 times smaller than the atom.

Given an atom with diameter of 100 picometers, the diameter in inches is 4 nano inches.
The atomic nucleus of hydrogen atom has a diameter of 1,75 femtometres.
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.

A hydrogen atom has the smallest diameter because there is only one proton and neutron.
A hydrogen atom has a diameter of about 60 picometers while a proton has a diameter of 1.75 femotometers. So a hydrogen atom's diameter is about 35,000 times that of a proton.
A sodium ion is smaller in diameter than a sodium atom.
what kind of atom there not all the same(1.75×10−15 m)this is the diameter of a hydrogen nucleus
That ratio is about 53,000.
