Exploring the Atomic Model Since Quantum Revolution

In summary, the atomic model currently "looks like" an electron is a particle that is not equally "spread out" along its standing wave. This means that when atoms bond, the waves superimpose each other. The wavefunction is not changed when atoms bond.

Hello,

I have a few questions concerning what the atomic model currently "looks like" since the quantum revolution.

I know that, since the wavefunction, electrons are in probability "clouds" and I know they are standing waves. So this would mean, technically speaking, that the electron is an element of matter, charge, and spin that is not equally "spread out" along its standing wave. So, when atoms bond, do these waves superimpose each other? Is the wavefunction changed when atoms bond? Also, is an electron still a complete standing wave even when it is not "orbiting" around a nucleus?

On entanglement, if an entire atom acts as one entity, then all of its consitutes are entangled and share a single wavefunction correct? If no, please explain.

Thanks to all those who respond

Well no an electron does not have an even probability distrubution if that's what youre asking. If you think back to the particle in a box idea, in order to make 'ends meet' ie make the function mathematically sound, it results in a function that is not flat but has a sineusodial motion.

In terms of bonding this is an overlap into chemsitry. If you look at the resulting electron cloud configurations from various bonds (it can get complicated when you get to or past transition metals and such) you can see that there is an interaction between the clouds, as to wether or not this is a simple superposition effect I am not sure but id imagine its a bit more complicated, but that's along the right lines of thinking, i think :P

As the atoms get closer together, electrons 'jump' from one atom to the other, and the same can be said of the opposite atom. This results in two waves, in opposite directions. In doing so, the waves superimpose on each other, which for jumping is similar to the electron being into different eigenstates at the same time, due to proability. All that can really be determined is that the probablility of finding the electrons in either of the atoms is 1. It is possible to restrict the radius and so the distance an electron can travel and so increase individual probabilities but that is about it.

I hope this helps, and is mostly right :biggrin:

1. What is the atomic model?

The atomic model is a scientific theory that describes the structure of an atom, the building blocks of matter. It explains how atoms are composed of a central nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in orbit around the nucleus.

2. What is the significance of the quantum revolution in the exploration of the atomic model?

The quantum revolution, also known as the quantum mechanics or quantum physics, was a major breakthrough in the field of physics that revolutionized our understanding of the atomic model. It provided a more accurate and detailed description of the behavior of subatomic particles, which was crucial in refining the atomic model and explaining phenomena that classical physics could not.

3. How has the atomic model evolved since the quantum revolution?

Since the quantum revolution, the atomic model has undergone several modifications as new discoveries and advancements in technology have allowed scientists to probe deeper into the structure of atoms.
