If the charges repel how does the positively charge nucleus of an atom stay together?

Answer 1

Strong nuclear forces hold them together.

Answer 2

The nucleus of any atom excluding hydrogen-1 (which has only one proton) is not composed of only of protons. There are also neutrons present in atoms which are responsible for the stabilization of protons. Please refer to the related question.

Answer 3

It is nuclear binding energy or residual strong force that overcomes the repulsive force between protons to bind atomic nuclei together.

When atomic nuclei are fused together in a fusion reaction, the "pieces" of matter that are fused undergo a change. This change is mediated by the strong force, which is the force that holds that quarks together to form protons and neutrons. All the protons and neutrons, which are called nucleons when talking about these particles as building blocks of an atomic nucleus, undergo a small loss of mass. This is the phenomenon of mass deficit, and that bit of mass that was "taken" from each nucleon is used to create the nuclear binding energy (or nuclear glue) that holds the atomic nucleus together.

Answer 4

In part, neutrons help to stabilize the nucleus because they add charge-neutral matter between protons. But this does not do much to help the problem (magnets still work through wooden desks, for example), and if neutrons were the only defense of the nucleus, atoms would fly apart. Fortunately, neutrons are not working alone.

There are four forces in nature. Two we know about by direct observation - gravity and electromagnetism. The other two are nuclear forces which act on very small scales, known respectively as the strong and weak nuclear forces.

In a nutshell, protons and neutrons are both made of smaller particles whimsically known as "quarks", which as far as we can tell are the most fundamental form of particle, along with electrons, neutrinos and force carrying particles. A proton is made of two "up" quarks and one "down" quark, while a neutron is made of two "downs" and one "up". These quarks are held together by gluons, small force-carrying particles which transmit the strong nuclear force.

The strong nuclear force is roughly 100 times stronger than the electromagnetic force trying to rip the nucleus apart. It has a very short area of effect, however; in larger nuclei, the strong force "drops off" near the outer edge of the nucleus and sometimes, a small bundle of protons and neutrons is able to escape. This is known as alpha decay, and occurs in nuclei too large to be fully stabilized by the combination of adding neutrons and the strength of the strong nuclear force.

So in general, the strong force and neutrons work in conjunction to keep nuclei from breaking up, but it doesn't alwayswork.

Answer 5

when the two positively charged protons or particles that electrically reples because any two same polarites are reppled each other and also the positive polarity present in the one proton can attracts only negative polarity only not positive polarity

Answer 6

A very good question! After all protons are positively charged so they should repel each other! Why does an atomic nucleus remain stable?

This has to do with the compositeness of the protons and neutrons. They both consist of quarks and quarks also feel the effects of another force than electromagnetism (which would drive the protons apart), they also feel the so-called strong nuclear force.

As the name suggests, this strong force is much stronger than electromagnetism, and it is this force that binds neutrons and protons together in the atomic nucleus.

The strong nuclear force acts on particles which have a non-white color charge. Each neutron or proton consists of three quarks; each of which has a different color (there are 3 in total: red, blue and green). The neutron or proton is neutral in color (i.e. white), but because the quarks inside them are not all located at the same point they do have a sort of color 'dipole' moment. This means that for example while the proton is globally white, one side might be slightly redder, while another side might be slightly greener. These 'residual' colors attract each other, binding the nucleus together.

Answer 7

The protons and the neutrons stay together because of the Strong Force, also known as the Nuclear Force.

Answer 8

The Stong force is, in this case, stronger than the Gravitational force.

Answer 9

Protons and Neutrons are bound together in a nucleus by the Strong Nuclear Force (aka the Strong Interactions). strong-interaction

Answer 10

Because protons are both positive therefore they repel. Opposites attract, Same repel.
