y protons being positive charge stay in the nucleus..??

Question

same charges repel.. protons dont repel in the nucleus.. caz if they do..nucleus wudnt have existed.. so.. protons come so close that they start attracting and hence the nucleus.. whts the reason????... whts the theory behind it?...

Answer 1

There are four basic forces in nature: gravity, electromagnetism, the strong force, and the weak force. When you say that positive charges repel each other, you are talking about the electromagnetic force. But for protons and electrons in the nucleus, the strong force is attractive to an extent that overcomes the repulsion of the electromagnetic force. Unfortunately, the strong force is the force we understand the least. We know the overall picture: quarks (which make up the protons and neutrons) exchange gluons and that produces the strong force. The problem is that the calculations necessary to really understand the process are incredibly difficult. In fact, one of the Millenium problems in mathematics is related to our theories of the strong force.

Answer 2

There are neutrons in the nucleus also. Between the protons and the neutrons exists the strong nuclear force, on of the fundimental forces of nature. This strong nuclear force is the 'glue' that holds the protons and the neutons together forming a nucleus.

On a graph of neutrons versus protons inside a nucleus the line a is straight 1 to 1 for lower numbers of protons, but the line curves towards the neutron axis as the number of protons increases. This is because the repulsive electrical charge between the protons is stronger and so more (than equal to the number of protons) neutrons are required to glue the nucleus together.

Answer 3

protons are found in the nucleus and they repell each other as well. neutrons are there as well and sorta act like a buffer because they have no charge. it's the overall positive charge that keeps the electrons where they are.
