The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
What keeps electrons from repelling each other?
The charge from one electron on another repel, but the positive nucleus keeps them bound, so the atom doesnt fall apart. Sometimes electrons can be removed rendering the atom as a +ion. Its the nuclear force which binds the electron in the atom. These are one of the four fundamental forces.
What keeps the protons within the nucleus from repelling each other?
Protons in nucleus no doubt are repelled by each other. But we know that an atom is stable. The reason for this is that the protons and the neutrons(together called nucleons) are attracted to each other by a strong for called nuclear force. This force acts only in the distances of orders of angstrom or picometre.
Why do electrons not repel each other?
The two electrons in a covalent bond usually have opposite spins, so they attract each other because of exchange force. However, they repel each other because of Coulomb forces, the resultant force makes them stable.
Why do 2 electrons repel?
Particles with the same charge repel each other, while oppositely charged particles attract each other. For example, a proton, which is positively charged, is attracted to electrons, which are negatively charged. … Figure 1: a) The two electrons are placed together and repel each other because of the same charge.
What keeps a nucleus together?
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
Why do protons in a nucleus stay together?
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
What does the stability of a nucleus depend on?
The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in the nucleus.
Why do electrons not stick to the nucleus?
Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, QM prohibits electrons from falling to the nucleus.
Which of the following would cause a nucleus to be unstable?
Instability of an atom’s nucleus may result from an excess of either neutrons or protons. A radioactive atom will attempt to reach stability by ejecting nucleons (protons or neutrons), as well as other particles, or by releasing energy in other forms.
