not at all
I think your question is garbled. Two people can repell each other, meaning that they have a mutual dislike, but they cannot repeal each other. Only laws can be repealed, and two laws cannot repeal each other. You could also be talking about magnets. Two north poles, or two south poles repell each other, meaning that they push each other away.
yup
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Only when very close to each other. This is not because of the electric force, it is because of the "strong force," or the emission and absorption of gluons between them. This also happens between neutrons and protons.
Protons and neutrons attract each other through the strong nuclear force, which is mediated by particles called mesons. This force overcomes the electromagnetic repulsion between the positively charged protons.
They are isotopes of each other
They have a different number of neutrons.
False. Neutrons do not repel each other. They are electrically neutral particles that are held together within an atomic nucleus by the strong nuclear force, which overcomes their repulsion due to the electromagnetic force.
no as the broken will repeal as they form same poles
They will have a different number of neutrons.
The number of neutrons is different.
Protons are positively charged Neutrons are negatively charged The number of protons is the atomic number Protons+Neutrons=Atomic weight
