What prevents electrons from falling into the nucleus?
If opposite charges attract, what stops electrons from crashing into the nucleus? Should they not be attracted to the protons?
Why do electrons and protons attract each other? Why don't protons in a nucleus repel each other? Wont positively charged protons lying together in the nucleus repel each other? Why doesn't the proton in a hydrogen nucleus pull in its electron? We say that like charges repel each other. How do protons remain stable in a nucleus in spite of having like charges? What happens when a proton and electron collide? Even if opposite charges repel each other why are all the protons attached at the same place in an atom? What happens when a proton and anti proton annihilate each other at non relativistic speeds? What would come out of this interaction? Why do electrons that are further from the nucleus have higher energy than electrons that are closer to the nucleus? How are protons separated from the nucleus? How often do electrons collide with the nucleus of an atom? Is there a reason that protons are positively charged and electrons are negative? Why doesn't two protons repel in an atom, as protons are positively charged and two like charges tend to repel? What happens if a electron from the K shell hits the nucleus? Will the nucleus of an atom move inside the atom when an electric field is applied? Who discovered the nucleus of atom is positively charge? What gives a proton its charge? Theoretically, is it possible for an atom to lose or expel all of its electrons? If so what happens to its nucleus? How are the charges of electrons and proton balanced? Why the electrons did not vanish from solar cell? If electromagnetic repulsion does not allow atoms to compress then why it is done in neutron stars? What is the charge of a proton? What is the charge on a proton? Can proton and neutron be separated from the nucleus? How? Why atoms becomes neutral when it shares electrons? Why do electrons repel each other? Why the atoms become neutral when it shares electron ? What are the best theories at present for the balance in charges of electrons and protons? How is magnetism related to electrons? If energy changes from one state to another, from where does an electron get it's energy to rotate around the nucleus?
