The nucleus is at the center of the atom because it is the most dense, massive portion of the atom (although, compared to the diameter of the atom, extremely small in surface area and volume). Also, because of its positive charge, the negatively charged electrons orbit around it.

Using heisenberg's uncertainity principle prove the non existence of the electron inside the nucleus?
The Heseinberg's Uncertainty Principle states that you cannot know the position and momentum of a particle simultaneously. More rigorously stated, the product of the uncertainty of the position of a particle (Δx) and the uncertainty of its momentum (Δp) must be greater than a specified value: ∆x∆p ≥ (h/4π) Now, as the electron approaches the nucleus, it's uncertainty in position decreases (if the electron is 10nm away from the nucleus, it could be anywhere within a spherical shell of radius 10nm, but if the electron is only 0.1nm away from the nucleus, that area is greatly reduced). According to the Heisenberg uncertainty principle, if you decrease the uncertainty of the electrons position, the uncertainty in its momentum must increase. This increased momentum uncertainty means that the electron will be moving away from the nucleus faster, on average. Put another way, if we do know that at one instant, that the electron is right on top of the nucleus, we lose all information about where the electron will be at the next instant. It could stay at the nucleus, it could be slightly to the left or to the right, or it could very likely be very far away from the nucleus. Therefore, because of the uncertainty principle it is impossible for the electron to fall into the nucleus and stay in the nucleus. In essence, the uncertainty principle causes a sort of quantum repulsion that keeps electrons from being too tightly localized near the nucleus.
Do electrons surround the nucleus?
In simple models, yes. They do. In a more correct and more complex model, it is not possible to determine the exact position of an electron at any point, (as they are quantum) but areas of high probability for the electrons to be in exist, they are called orbitals, and yes, they surround the nucleus in a manner of speaking. In metallic bonding, the electrons de-localise from the orbitals, and they float around the substance. These electrons are not surrounding the nucleus.
Was rutherfords model of the atom incorrect or incomplete?
Rutherford's model of the atom was one that resembled the solar system. The nucleus took the place of the sun, at the centre. The electrons followed well-defined orbits around the nucleus so that it should be possible to determine the location and motion of the electrons. In fact, electrons orbit the nucleus in a cloud. It is not possible to know their position and momentum at the same time.
Picture of a nucleus?
I need a picture of a nucleus can i please get a picture of a nucleus
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
What is a protons position in the atom?
its in the nucleus
What is the nucleus position in a plant cell?
through the root
Where is the position of the nucleus in a cell?
The nucleus is found in the center of the cytoplasm of the cell. The nucleus is not always in the center of the cell and it is never situated too close to the cell wall.
Is the nucleus in squamous cells centrally located?
not necessarily , it can be at any position .
What is the position of the electrons in Bohr'smodel?
Defined orbits around nucleus, no uncertainty principle
What are barrel shaped organelles that help position the nucleus and other organelles?
Centrioles
What phrases describes how the position of an electron relates to its energy?
The farther an electron is from the nucleus, the greater its energy.
What describes how the position of an electron relates to it's energy?
The farther an electron is from the nucleus, the greater its energy.
Do proton have position inside or the outside the nucleus?
Protons are located within the nucleus of the atom. The mass of an atom is made up of majorly; neutrons and protons (both located within the nucleus). The mass of an electron is almost negligible(non-existent).
Are neutrons inside or circling the nucleus?
Electrons surround the nucleus of an atom. The classical model shows them circling but in fact, their position and path is more complicated. The nucleus is made up of protons and neutrons. Protein is a molecule, not a component of atoms.
What does the nuclueus do?
It directs the cell's activities, functions, structure. It's pretty much the "brain" of the cell.The Nucleolus is like nucleus in a nucleus. It does the same exact task, but is the HEADQUARTERS, the highest position of direction.
What two factors determine the location of an electron around the nucleus?
neutrons and protons
