Discussion Overview
The discussion revolves around comparing the Radial Distribution Function for the 1s and 2s orbitals, focusing on maximum electron density. Participants explore this concept in the context of atomic structure and electron configurations.
Discussion Character
- Homework-related
- Debate/contested
Main Points Raised
- One participant suggests comparing plots for the 1s and 2s orbitals to determine which has a higher maximum electron density.
- Another participant emphasizes the need to compare plots for the same atom, specifically mentioning hydrogen.
- A later reply asserts that in every atom, the 1s orbital has a higher maximum electron density, clarifying that "higher maximum density" is distinct from "more density."
- Several participants express confusion regarding the application of provided formulas and data, indicating a lack of clarity in the homework assignment.
- One participant mentions learning more effectively through video classes compared to traditional instruction.
Areas of Agreement / Disagreement
There is no consensus on the specifics of the comparison, as participants express differing levels of understanding and confusion about the homework requirements. Some participants agree that the 1s orbital has a higher maximum electron density, while others are still seeking clarification.
Contextual Notes
Participants reference specific formulas and data related to energy levels and photon energy, but there is uncertainty about how to apply this information to the original question regarding the Radial Distribution Function.

Just look at the plot - which function has a higher maximum electron density?

No.
You need to compare plots for the same atom, not for different atoms.

Ahhh... I think the hydrogen has more density for in the 1s level.

Am I correct now, professor?

I had this class, but my professor doesn't explain good. I learn more with videoclasses on Youtube than with him.

Don't professor me.
Yes, in _every_ atom 1s orbital has a higher maximum electron density. Note: it is important to be precise, "higher maximum density" means something else than "more density".

Good mornig, Borek!
So, The data that my professor gave was:
En = -2,18 x 10-18 x (1/n²) x Z² Joules, where En is the energy from the n level, Z = atomic number.
.v = c; Efoton = h.v; h = 6,626 x 10-34 J s; c = 3,00 x 108 m s -1;
Spectrum in the visible: 400 to 700nm
I don't know how to do this question with these data.

I think that this question has been answered. What your professor gave you is relevant to the other thread that you started hereJosé Ricardo said:Good mornig, Borek!
