same pole and charge repell each other then how protons with same charge are contained in nucleus?

Answer 1

You have a good question. The neutrons separate the protons and keep them from fighting. As atoms get bigger they have more neutrons. In the smaller ones there is about the same number of protons and neutrons. In the bigger ones there is more than twice as many neutrons as protons. The ones with too few neutrons are the more unstable ones that tend to decompose radioactively.

uranium is number 92, 92 protons. Its weight is 238. there are 146 neutrons to separate those protons. U-235 is more radioactive ,fewer neutrons

Answer 2

This is a simple question...Protons do indeed repel each other through electric force. However, there is a stronger force holding them together. This is called the strong force. It is believed to act through the sharing of gluons, particles that act like glue between nucleoli, nuclear particles.
Again, the strong force overcomes the electric repulsion. However, in atoms with more that 83 protons, everything heavier than bismuth, the electric force can overcome the strong force. In other words, all eemnts heavier than Bismuth are radioactive.

Answer 3

The strong nuclear force holds them together. I guess this probably sounds kind of weird because you don't see the strong force affecting things on a day to day basis. The reason why this works with protons and neutrons is because the strong force has a VERY short range over which it is effective. Since protons and neutrons are really super close together, it helps to bind them together to form nuclei.

Answer 4

While it's true that the electromagnetic forces between the protons are trying to tear the nucleus apart, there is a stronger force that holds them together. This is called the Strong Nuclear Force, and it is always attractive, but it only works over very short distances. There is also a Weak Nuclear Force, which causes nuclear decay. Electromagnetic forces are weaker, and gravity is very, very weak.

Answer 5

in the nucleus there are protons and neutrons of equal amount except in the case of isotopes. the protons are attached to the neutrons which keep them intact so the don't spread out.

Answer 6

Protons and neutrons are held together through gluons, which are subatomic particles that cause quarks to interact.
