Help Understanding Qualitative Band Diagrams for F-Chain

AI Thread Summary
The discussion revolves around constructing qualitative band diagrams for an infinite fluorine chain, specifically addressing the confusion around electron configurations at k=0. The user understands that there are four bands corresponding to the four orbitals but is unclear why the 2pz orbital is antibonding at k=0. They recognize that at k=π/2, the states are opposite but struggle with determining the initial state. The thread also suggests that rephrasing the question or providing additional details might help generate responses. Overall, the inquiry focuses on understanding the band structure and orbital characteristics in the context of solid-state physics.

Homework Statement


Hi everyone, I am trying to construct qualitative band diagrams and I think I have confused myself. I am not sure on how to figure out what the electron configurations are of the orbitals when k=0. I get that at k=π/2 it is the opposite state but I can't seem to figure out how to get the initial state. The problem I am working on is an infinite Florine chain at the moment.

Homework Equations

The Attempt at a Solution


I know it has 4 bands due to it's four orbitals but I can't figure out why at k=0 the 2pz orbital is antibonding. Thanks for the help.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
