That is a nonsense question because there is no measurement unit for length which is 10 mn. The nearest candidate is nm (nanometre) but the diameter of an hydrogen atom is nowhere near 10 nm.
The diameter of a gold atom is approximately 0.288 nanometers.
The diameter of the nucleus of a hydrogen atom is approximately 1 femtometer (10^-15 meters). However, since the electron cloud extends much further beyond the nucleus, the overall diameter of a hydrogen atom is on the order of 100 picometers (10^-10 meters).
The diameter of a helium atom is approximately 0.1 nanometers, or 1 angstrom. In meters, this translates to about 1 × 10^-10 meters. Helium atoms are among the smallest atoms, with their size largely determined by the electron cloud surrounding the nucleus.
The answer for a hydrogen atom would be about 100 meters across a proton is about 1/10,000 th of the diameter of a hydrogen atom.
An atoms has a diameter of about 1x10^-10 meters to about 5x10^-10 meters. Using the larger number, and making it 1 million times bigger, you would have something with a diameter of5x10^-10 meters x 1x10^6 = 5x10^-4 meters, or put another way, the diameter would be about 0.5 mm
The diameter of a hydrogen atom is roughly 100,000 times larger than the diameter of a proton.
The diameter of a xenon atom is approximately 0.216 nanometers.
The diameter of an atom is 5 x 10^-8 centimeters.
The diameter of a phosphorus atom is approximately 100 picometers.
A hydrogen atom has the smallest diameter because there is only one proton and neutron.
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.
The diameter of the nucleus is several orders of magnitude smaller than the diameter of the atom. The nucleus is approximately 10,000 times smaller than the overall size of the atom.
