Why does ψ^2 ( square of orbital wave function ψ) give the probability of an electron in a given region? [duplicate]
Today I was introduced to the Orbital Wave Function for electrons.
$\Psi$ is a mathematical function for coordinate of electrons and has no physical meaning.
But $\Psi^2$ gives probability of an ...

Electron pairing in atoms
A question asks:
This question refers to isolated gaseous atoms. In which atom are all electrons paired? Ba, Br, S or Si?
I thought it was Ba as its electron configuration is [Xe] 6s2.
However, ...

How did Thomson calculate the momentum of electron when he didn't know the mass of electron?
This was proven in 1903 by J. J. Thomson who calculated that the momentum of the electrons hitting the paddle wheel would only be sufficient to turn the wheel one revolution per minute. source
J. J. ...

What will happen if electron as a wave undergo destructive interference while travelling in its Orbit?
Today I came across a justification of Bohr's angular momentum quantization using the De- Broglie's hypothesis.
The justification said that since the electrons are having wave nature also then while ...

Deducing the shell when transition occurs such that two photons are discharged
Find $n$ (quantum number) corresponding to the excited state of $\ce{He+}$ ion if on transition to ground state the ion emits two photons in succession with wavelengths $\pu{108.5 nm}$ and $\pu{30.4 ...

Why did J.J. Thomson observe protons in his cathode ray experiment?
In this MIT lecture, at 7:22, the professor says that when J.J. Thomson added a positively charged plate on one side of the cathode ray and a negatively charged plate on the other side, he observed a ...

Quantization and Bohr's model
According to quantization it's said that emitted or absorbed energy is quantized.
Then, when it's said in bohr's model an electron changes its orbit (Let's say it goes to a higher energy shell from $...

Why is there an orbital angular momentum if the electron isn't properly revolving around the nucleus?
I'm a tenth grader who's just been introduced to this subject of atomic structure, so please help.
I recently read that an electron doesn't have circular motion around a nucleus, its motion is kind ...

Do electrons have some volume, area or shape?
I am in 8th grade now and when I was in 6th grade, my science book had diagrams of the electronic configuration of atoms. The electrons were round like spherical balls. Is it true that the electrons ...

Why do objects gain electrons? [duplicate]
I have read that objects gain electrons to become negatively charged and also that they lose electrons to become positively charged. I have also read that same charges repel each other and non-same ...

Volume of orbitals
As I was learning about atomic structure, the lecturer made a seemingly dubious claim:
The volume of a p orbital is one-third that of the s orbital. Thus, inter-electronic repulsions are ...
