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.
An electron is smaller than a nucleus. Electrons are elementary particles that orbit the nucleus of an atom, which is made up of protons and neutrons. The nucleus is much larger and contains most of the mass of an atom.
It 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 are an atoms nucleus and its electron cloud different?
The nucleus of an atom contains protons and neutrons, while the electron cloud surrounds the nucleus and contains the electrons. The nucleus is positively charged and is much smaller in size compared to the electron cloud. The electron cloud determines the size of the atom and contains most of the atom's volume.
What is a smaller atomic radius of beryllium be?
A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
How the electron population ig aluminium is lessthan boron?
Aluminum has one more proton in its nucleus compared to boron, creating a stronger positive charge that attracts electrons more strongly. This stronger attraction results in aluminum pulling its electrons closer to the nucleus, creating a smaller electron cloud and therefore a smaller electron population compared to boron.
How can you use atom electron nucleus and electron cloud in the same sentence?
The atom's nucleus contains protons and neutrons, while electrons are found in the electron cloud surrounding the nucleus.
Why are sodium ions smaller than sodium atoms?
Sodium ions are smaller than sodium atoms because when sodium atoms lose an electron to become an ion, they lose the outermost electron from their electron cloud. This results in a decrease in the electron cloud size around the nucleus, making the ion smaller than the neutral atom.
An electron is much larger than an atom?
This statement is not correct. An atom is made up of a nucleus (containing protons and neutrons) surrounded by electrons. Electrons are subatomic particles that are much smaller and have much less mass than the nucleus of an atom.
Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
The magnetic moment of a nucleus is generally smaller than that of an electron because the nucleus is composed of protons and neutrons, which have smaller individual magnetic moments that partially cancel each other out due to their arrangement within the nucleus. Electrons, on the other hand, are elementary particles with a specific magnetic moment that is not cancelled out by other particles.
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.
How are an atoms nucleus and its electron cloud different?
The nucleus of an atom contains protons and neutrons, while the electron cloud surrounds the nucleus and contains the electrons. The nucleus is positively charged and is much smaller in size compared to the electron cloud. The electron cloud determines the size of the atom and contains most of the atom's volume.
Is a electron smaller than a neutron?
Yes, an electron is smaller than a neutron. An electron is a fundamental particle and has a much smaller mass than a neutron, which is made up of quarks.
As the distance between a nucleus and an orbital electron increases the electrical force of?
Attraction gets smaller.
What is a smaller atomic radius of beryllium be?
A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
The majority of the atom's mass is found in the?
The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.
Where is most of the mass of an element located?
Most of the mass of an element is located in the nucleus, which contains protons and neutrons. Electrons, which have a much smaller mass, are located in the electron cloud surrounding the nucleus.
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 the electron population ig aluminium is lessthan boron?
Aluminum has one more proton in its nucleus compared to boron, creating a stronger positive charge that attracts electrons more strongly. This stronger attraction results in aluminum pulling its electrons closer to the nucleus, creating a smaller electron cloud and therefore a smaller electron population compared to boron.
