What is Atomic physics: Definition and 107 Discussions
Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and
the processes by which these arrangements change. This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions.
The term atomic physics can be associated with nuclear power and nuclear weapons, due to the synonymous use of atomic and nuclear in standard English. Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics, which studies nuclear reactions and special properties of atomic nuclei.
As with many scientific fields, strict delineation can be highly contrived and atomic physics is often considered in the wider context of atomic, molecular, and optical physics. Physics research groups are usually so classified.

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...
