what is the force that holds the protons and neutrons together in a nucleus?

Question

i mean, the name of the force. help me..!!

thanks gorgeous! love yah!

Answer 1

Many theories are available. To understand this you need to think beyond fundamental particle, That is fundamental particles, themselves are composite of some other more elementry particles(both mass and charge..)

The simplest and the most acceptable theory is that, at nucleus a neutron looses an electron to become a proton and the lost electron is absorbed by a proton to become a neutron. This creates distribution of charges to neutralize the very strong proton-proton repulsion.

Many other are theories can explain the behavior to some extent.

Answer 2

um... that would be the 'strong force'. that would be the one that releases all of the energy when the chain reaction of a nuke makes the big explosion. it is simply called the strong force, because it appears to overcome many other forces that might tend to break the nucleus apart. the nucleus is made up of protons (which tend to repel each other) and perhaps several neutrons (which are neutral in electromagnetic force). the force required to hold more than one proton close together in a single nucleus (against all their EM repelling forces must be very strong. stronger than the weaker forces of EM that keep the electron orbiting the nucleus. certainly stronger than the force of gravity that lets us pick up a pencil when the entire earth is pulling against it.

the name of the force you are looking for is the 'strong force'. simply enough.

Answer 3

It's the magnetic attraction between positive and negative particles. Magnetic Dear, love yah back!

Answer 4

The strong nuclear force it also prevents them from merging into a thermonuclear explosion.

Answer 5

It is called the strong nuclear force.
