In a eukaryote cell (i.e plants and animals) the nucleus is around 10um and is pretty spherical in shape. Bacterial cells do not have nuclei, but instead have most of the DNA bundled up in a nucleoli - which has no real shape (just a tangle of DNA) and no surrounding membrane.

How does the size of an atomic nucleus compare with the size of the whole atom?
Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
How big is the nucleus compared to the atom as a whole?
Not very big. The nucleus of an atom, the part containing protons and neutrons (1H, protium, consists of only a proton and an electron) takes up only a tiny portion of the atom's volume. The volume of an atom is really described by the movement of the electrons that orbit about the nucleus. Those electrons are a looooong way from the proton(s) relative to their size. A nucleus is about 10 FM in diameter. In a solid, nuclei are 1000000 or more FM apart. Hydrogen is small compared to other atoms. To scale it up: if the proton in its nucleus was enlarged to the size of a basketball, the electron would be some 20 miles away or so. With other atoms, the picture gets more crazy. The reality is that an atom is mostly space, and you've probably heard that. The nucleus of an atom is super tiny compared to the 95% boundary described by the outer electrons of an atom. The boundary can't be well-defined, really, because of what quantum mechanics, the uncertainty principle, and Schroedinger's wave equation have to say.
What did Rutherford proposed?
He proposed a new model of the atom in which there is a small dense positively charged nucleus with negatively charged electrons around the outside. The electrons are far away in comparison to the size of nucleus, so the majority of the atom is made up of empty space.
How many times smaller is the nucleus than the atom?
Well, honey, the nucleus is about 100,000 times smaller than the whole atom. It's like comparing a pea to a watermelon - one's a tiny powerhouse, and the other's just there for show. Just remember, size isn't everything, especially in the world of atoms.
What controls the center of a cell?
nucleus nucleus
Is 0.006 the approxment size of a nucleus?
No, the typical size of a nucleus is on the order of femtometers (10^-15 meters). The size of a nucleus is much smaller than 0.006 meters.
What is a reasonable estimate for the size of a cell nucleus?
What reasonable estimate for the size of a cell's nucleus?
How is knowledge about the size of the atomic nucleus is based on probability?
The size of a nucleus may be measured by firing sub-atomic particles at the nucleus and counting the proportion that bounce off the nucleus rather than miss it entirely. Assuming that the nucleus is spherical in shape, the ratio allows its size to be estimated.
How does the size of an atomic nucleus compare with the size of the whole atom?
Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
How much would a nucleus the size of a grape weigh?
A nucleus the size of a grape would weigh virtually nothing, as the vast majority of an atom's mass is contained in its nucleus, which is incredibly tiny compared to the size of a grape.
Why the size of atom is biggest than nucleus?
The size of an atom is bigger than the nucleus because an atom consists of a nucleus surrounded by electron clouds. The electrons are located further away from the nucleus, leading to the overall larger size of the atom.
Who discovered the size of the nucleus scattering?
Rutherford
Where is the proton located in an atom?
In the nucleus of the atom, along with neutrons. The electrons are found around the nucleus. If the atom was the size of a Baseball stadium, the nucleus would be the size of a baseball! Most of the space in an atom is taken up by the electron cloud which surrounds the nucleus. That is why atoms are actually mostly empty space.
What is the approximate size of nucleus?
Nucleus of a cell ~10-7 - 10-6 m Atomic nucleus ~10-14 m
What is the size of an atomic nucleus?
The size of an atomic nucleus is typically on the order of femtometers (10^-15 meters), which is much smaller than the size of the atom itself. The nucleus contains protons and neutrons tightly packed together in a small volume at the center of the atom.
If an atom were the size of a baseball stadium its nucleus would be about the size of what?
If an atom were the size of a baseball stadium, its nucleus would be roughly the size of a marble or a small cherry. This analogy highlights the vast amount of empty space within an atom, with the nucleus occupying only a tiny fraction of the atom's overall volume. The electrons would be orbiting far away from the nucleus, much like spectators in the stands.
An atomic neucleus has a diameter of aproxamiately?
Depends a carbon nucleus is 40 times the size of an hydrogen nucleus.
