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 ...

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?...

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 ...

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 ...

Is Coulomb's law correct? [duplicate]

Why don't electrons and protons collide? Hydrogen atoms are often ionized. After ionization, it is divided into electrons and protons, which can merge into hydrogen atoms at any time. Why don't ...

Why does electron $(-)$ keep rotating round the nucleus $(+)$ even they are attracted? [duplicate]

I'm a secondary school pupil, my physics textbook discussed atomic physics without deep details because we are young boys, to explain electron motion we first learn about rotational motion. The main ...

Brehmsstrahlung radiation query - If an electron is constantly being decelerated, how does it emit a photon with a fixed energy?

According to my textbook they simply say an electron is decelerated by a nuclei and this means it loses KE. The difference in KE is given off as a photon. But an electron is always being pulled back ...

Why atoms do not radiate energy? [duplicate]

In atoms electron moves in a circular motion with constant velocity but in circular motion acceleration is produced when we change direction so we cant get constant velocity. So why electron do not ...

Do electron really experience any repulsive force while attracted by proton compared to positron?

I read up that the reason 2 electrons with same energy states can be binded to the first orbital of a necleus is due to one electron having positive spin half and another having negative spin half ...

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 ...

How can an ion ever capture an electron if an electron requires a precise momentum to match a subsequent orbital?

Suppose an electron approaches a proton with greater energy than the hydrogen ground state. Will the electron scatter? If so, how could an electron ever be captured given it would require exactly the ...
