Doesn't one proton repel the other?

Question

In an atom, the electrons revolve around the nucleus in orbits. That's ok.
But in the nucleus, the protons and nuetrons stay together.
How is that possible?
I mean, nuetrons do not have any charge.
So...why aren't the protons thrown away from each other???

Answer 1

Think of it this way. If you got two small magnets you could push the two north poles together with your hands. You're using a stronger force to defeat a weaker one. The same thing applies to protons, a stronger force inside the nucleus (called the Strong force) keeps the protons close together. Infact the Strong force is about 100 x more powerful than the electromagnetic force (which is what makes protons repel each other) so if you get atoms with about 100 protons in the nucleus the Strong force finds it difficult to keep hold of them all and occassionally bits of the nucleus escape. This is one form of radioactivity and explains why heavy atoms like Uranium are unstable.

Answer 2

They certainly do.... their electric charges do repel. But the Strong Nuclear Force keeps the nuclei together. It is another fundamental force, like gravity or electromagnetism; it is by far the strongest force but it only works over very short range -- like, within a nucleus. There is also the Weak Nuclear Force, another short range force that breaks nuclei apart during atomic fission.

Gravity and electromagnetism are much, much, much weaker than the nuclear forces, but they work over unlimited range. But since gravity, the weakest fundamental force of all, is always attractive it becomes dominant in large scale phenomena (holding the planet together, or molding the universe). Electromagnetic forces can be attractive or repulsive. and so those tend to balance out with large quantities of matter.

Answer 3

There is a force acting within the nucleons commonly called Strong Force because it is very strong.
The strong force attracts the nucleons together, and counters the electrostatic force of repulsion.
In light nuclei, the strong force is predominant over the electrostatic force.
However in heavy nuclei, the repulsion prevails, and that is why they break apart.
In uranium, the strong force exactly counters the repulsion. So Uranium is the heaviest element naturally obtained.
Nuclei heavier than Uranium are highly unstable and break apart to form lighter nuclei..

Answer 4

Of course they repel each other

But since they're all enclosed in the nucleus, they r not ALLOWED to move away. Thats y, nuclear force is high. As soon as the nucleus breaks, that high tension created between the nucleons is transferred into energy which is known as nuclear energy!!!

Answer 5

in side the atom all nuclear forces are attraction forces and there are three attraction forces 1. bet neutrons and neutrons ( due to the exchange of the meson ) or ( the neutrons have the ability to be +ve or -ve as they have a +_ charge(the neutral charge) so if one became +ve the other have to turn into -ve)
2. bet protons and protons ( due to the effect of the mass ) or ( bec protons have a heavy mass that make it localized in its place and they can't throw each other)
3. bet protons and neutrons (as the +ve proton attracted to the -ve part of neutrons)
