Unveiling the Mysteries of the Electron in an Atom: The Quantum Perspective

In summary, quantum physicists have observed that an electron seems to be present in multiple locations at once, which goes against our traditional understanding of matter. This concept is difficult to grasp and often misrepresented in popular explanations. Even the most advanced explanations, like Feynman's, have some inaccuracies.

The quantum physicists claim, that an electron has been 'smeared out' in the space around the nucleus.
So it seems an electron in the atom is present everywhere at once.

Is the next interpretation acceptable?

The electron moves with many km/s in an extremely small space.
In photography it would give motion blur.
So the electron shows noting but motion blur.

No, this is not an acceptable interpretation.

You could get that view reading populist accounts - but its wrong.

Here is something explaining what QM REALLY is:
https://www.scottaaronson.com/democritus/lec9.html

That's what popularization's should explain - but don't. Instead they introduce all sorts of stuff that must be unlearned later like wave-particle duality and collapse.

Feynman's classic is still the best of the current lot IMHO:
https://en.wikipedia.org/wiki/QED:_The_Strange_Theory_of_Light_and_Matter

But, without going into details, even that at the very advanced level has some issues - Feynman isn't quite right when he says he will be giving you what doesn't need to be unlearned later - its nearly right in the sense you need to be very advanced to see it (it involves things like phonons and what not to describe the real interaction between light and matter) - but I will be telling a porky if I said its 100% correct.

Thanks

1. What is the electron and how does it contribute to the structure of an atom?

The electron is a subatomic particle that carries a negative charge. It is one of the fundamental building blocks of matter and is found orbiting around the nucleus of an atom. The number of electrons in an atom determines its chemical properties and overall stability.

2. How does quantum theory explain the behavior of electrons in an atom?

Quantum theory describes the behavior of electrons in an atom as a wave-particle duality. This means that electrons can act as both a wave and a particle, depending on the circumstances. This theory also states that the exact position and momentum of an electron cannot be simultaneously known, only probabilities of where it may be found.

3. What is an electron shell and how does it relate to an atom's energy levels?

An electron shell is a region of space surrounding the nucleus of an atom where electrons are most likely to be found. These shells are organized into different energy levels, with the electrons in the inner shells having lower energies than those in the outer shells. As electrons move between shells, they can absorb or release energy, which contributes to an atom's overall stability.

4. How do electrons contribute to the formation of chemical bonds?

Electrons play a crucial role in the formation of chemical bonds between atoms. By sharing, gaining, or losing electrons, atoms can achieve a stable electron configuration similar to that of a noble gas. This allows atoms to bond together and form molecules, which make up the substances around us.

5. Can electrons exist at multiple energy levels simultaneously?

According to quantum theory, electrons can exist at multiple energy levels simultaneously, but the probability of finding them in a specific energy level depends on the conditions and measurements. This concept is known as superposition and is a fundamental aspect of quantum mechanics.
