Atomic nuclei are much-much smaller than cell nuclei.
Why? Because a cell nucleus contains an enormous number of molecules, each molecule built from a number of atoms, with every single atom containing a tiny little (atomic) nucleus. For instance, an oxygen atom (which is a common component of living cells - think about water, H2O) is about 20 thousand times larger in diameter than its (atomic) nucleus.
Actually, if you magnified a typical cell nucleus (6 μm of diameter for average mammalian cells) to the size of the Earth (diameter of Earth: 12756.2 km), then the oxygen's atomic nucleus (actual diameter: 5.4 fm) would look like a half-inch (12.8 mm) ball at the same magnification.
That means that - as far as size is concerned - the atomic nucleus compares to the cell nucleus as a blueberry (or a smaller hazelnut) compares to our planet.

∙ 14y agoIt depends on what you mean by "small." The nucleus contains essentially all the mass of the atom, so in terms of mass an electron is much smaller than either an atom or a nucleus. However, the volume occupied by the electrons in an atom is essentially the same as the volume of the atom itself. The nucleus is much, much smaller in extent.

How can you use atom electron nucleus and electron cloud in the same sentence?
Electron in an atom is represented by electron cloud around the nucleus
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital?
An electron in a 2s orbital is on average closer to the nucleus.
The particle NOT found in the nucleus of the atom is what?
The particle not found in the nucleus is the electron
Will Lithium Sodium or Potassium react the fastest?
As it has more electron shells between the nucleus and the outermost electron, and as group 1 elements react by losing there outermost electron, the more shielding effect between the nucleus and the electron, the smaller the force of attraction on the electron, so the more readily it will react as less energy is needed to break the bond between the outer electron and the positive nucleus.
What are the differences between a proton and an electron?
a proton is a part of the atom, more specifically the nucleus (which also contains neutrons) and the electron is an even smaller particle that rotates around the nucleus of the atom and has a mass so minuscule even to an atom it is generally given the weight of zero.
Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
Because the charge/mass ratio of a nucleus is smaller than the charge/mass ratio of an electron
An electron is much larger than an atom?
an electron is much much smaller than an atom. An electron is a portion of the nucleus in an atom.
What ar the three smaller subatomic particles that make up an atom?
A electron(s) in a orbital around a nucleus made of protons and neutrons.
As the distance between a nucleus and an orbital electron increases the electrical force of?
Attraction gets smaller.
The farther an electron is from the nucleus the?
The farther an electron is from the nucleus, the greater its energy.
Where are the nucleus and electron cloud?
nucleus is in the middle and the electron cloud is around it
How can you use atom electron nucleus and electron cloud in the same sentence?
Electron in an atom is represented by electron cloud around the nucleus
Does the nucleus have the greatest mass in an atom?
An electron is not the largest part of an atom.An electron is the smallest component of an atom. Relatively, if a neutron or proton were 1 unit in size, an electron would be 1/1840 units in size. :3Read more: An_electron_is_the_largest_part_of_an_atom
Is the nucleus a region in which there is a good chance of finding an electron?
An electron is what orbits the nucleus. The nucleus is made of protons and neutrons
The particle NOT found in the nucleus of the atom is what?
The particle not found in the nucleus is the electron
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital?
An electron in a 2s orbital is on average closer to the nucleus.
Where is the location of an electron outside of the nucleus?
Electrons are found in the electron cloud that surrounds the nucleus.
