### Question about the orbits of electrons [duplicate]

A friend recently asked me the question, "If electrons have a negative charge and the nuclei of atoms have a positive charge, why don't electrons simply collapse into the nucleus and sit on it?". I ...

### Why electron moving with acceleration around nucleus is not emitting EM-waves? [duplicate]

I know that physics (beginnig with Bohr) say that while an electron is in any orbit (whle not jumping from orbit to orbit) it is not radiating EM-waves. But an electron in any orbit (even maximum ...

### What force counteracts the electrostatic attraction of an electron in an atom? [duplicate]

We all know it is not the centrifugal force. Given that the probability density multiplied by the surface area of a shell peaks at some distance from the nucleus. Also given that the electron in the ...

### Why Electron Does Not Radiate In Bohr Orbits? [duplicate]

Maxwell said that charged particles radiate when are in accelarating motion. I understand that $nλ=2πr$ must be fulfilled in order to create a sinusoidal standing wave and to satisfy the probability ...

### Which phenomenon makes the electrons revolve around the nucleus instead of crashing into it? [duplicate]

If the system has to gain stability, the electrons must crash into the nucleus but that's not the case.

### How is Schrodinger's model of atom consistent with reference to Maxwell's Theory of Electromagnetic Radiation? [duplicate]

When Rutherford proposed his model of atom, he mentioned that "Nucleus is surrounded by electrons that move around the nucleus with very high speed in circular paths called orbits. James Maxwell ...

### What is it that makes an electron maintain a distance from the positively charged nucleus? [duplicate]

What is it that makes an electron maintain a distance from the positively charged nucleus? Why aren't electrons merely pulled into and absorbed by the nucleus ?

### Why Does Electron Revolve around nucleus? [duplicate]

Actually why does electron revolve around nucleus. Considering Simple atom, hydrogen atom where a single electron revolves around the nucleus. It is said that the electrostatic force of attraction ...

### How to prove that atoms exist? More precisely - how come electrons and protons do not fall into each other? [duplicate]

Basically the question that I'm asking. Sure - There are few interactions that take the expected effect - electromagnetic, gravitational, strong and weak interactions. But how can we prove it, exactly?...

### Do all accelerating charge emit EM radiation? [duplicate]

A nucleus and an electron attract each other, so if they are to remain apart, the energy of the electron’s movement must balance the energy of attraction. However, the laws of physics had previously ...

### Circular motion of electrons around nucleus [duplicate]

We know that electrons are revolving around the nucleus because of the electrostatic force .But if the electron is moving in circular path then as acceleration has to be in inward direction due to a ...

### Why do electrons occupy the space around nuclei, and not collide with them?

We all learn in grade school that electrons are negatively-charged particles that inhabit the space around the nucleus of an atom, that protons are positively-charged and are embedded within the ...

### Why don't loop currents produce light?

If a charge travels in a circle it must accelerate, thereby producing EM. However, a wire in a circular loop is analogous to many charges moving in a circle. So, why don't circular currents produce ...
