I am taking a atomic-molcular physics class right now and we are suposed to hold a 25 minute presentation in 4 weeks on a hot topic in atomic-molecular physics.
If possible Il gladly take this as a chanse to deepen my knoweledge on...
Describe briefly one piece of evidence for each of the following statements.
i) Atomic radii are about 10^-10m
ii) Nuclear radii are about 10^-14m
Each part is worth 4 marks, so I would really appreciate if someone could reply with some slightly easy to understand, but quite detailed...
Hi, I've been trying to figure these two questions out but they haven't beeen working.
1. A hydrogen atom is in its fifth excited state. The atom emits a 1090 nm wavelength photon. Determine the maximum possible orbital angular momentum of the electron after emission. Express your answer as...
i am having problems with the atom model part of physics, i know that the current model stats the electron location is a probability and all, its when i get to the wavelength and the energy, with all the ionization and the spectrums that i don't understand...
how can i find the energy level...
