Well it is not a fixed ratio, each element has its own diameter for the atom and nucleus depending on atomic number and atomic weight. but an idea can be given: for a certain elemnt the atom daimeter is 225 picometer and the nucleus diameter is 6 femtometer ,the ratio would be ( 225x 10^ - 12) /(6x 10^ - 15)= 37500.

Can you explain why the estimation of the diameter of an atom is greater or less than the known value?
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.
How does the mass of a nucleus compare to a electron?
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
What is the fraction for the nucleus?
The answer will depend on what nucleus the question refers to. The nucleus of a cell is quite different from a nucleus of an atom. which differs from the nucleus of an organisation.
What three subatomic particles are found in the nucleus?
The nucleus of an atom contains only protons and neutrons. Electrons orbit the nucleus.
The number of these will determine it's atomic number?
The atomic number of any atom is determined by the number of protons in the nucleus of the atom.
How much larger is the diameter of the entire atom compared to the diameter of its nucleus?
100,000 times.
How does the diameter of the nucleus compare to the diameter of the atom?
what kind of atom there not all the same(1.75×10−15 m)this is the diameter of a hydrogen nucleus

Diameter of the center of the atom of hydrogen?
The atomic nucleus of hydrogen atom has a diameter of 1,75 femtometres.
How many meters is an atom meter?
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.
How does the volume of a nucleus to the volume of an atom?
the volume of atom is much greater than that of nucleus
How does the volume of a nucleus compare to the volume of an atom?
the volume of atom is much greater than that of nucleus
What makes an iron atom have a greater mass than an aliminium atom?
The amount of protons in the nucleus of an iron atom is greater than in that of an aluminum atom.
How many times smaller is the nucleus than the atom?
The atom has roughly 1E15 times the volume of its nucleus.
What percent of the atom is free space empty of mass?
If the atom's outer boundary is established by the "mean radius of the outermost electron orbital" or something like that, the atom is waaaaaaaaaaay over 99% free space. The hydrogen atom has a diameter over 100,000 times the diameter of the proton in it's nucleus.
Diameter of hydrogen atom compared to nucleus?
The ratio (for the covalent radius of the atom) is cca. 1/25000.
The diameter of an atom is?
in the bottom Atomic nucleus is at the center of the atom.
