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 includes ions as well as neutral atoms and, unless otherwise stated, for the purposes of this discussion it should be assumed that the term atom includes ions.

What is the relationship between wavelength and energy to an electron in an atom orbit?

From this law: $2\pi r=n\lambda$. if the radius of the atomic orbit increases the wavelength of the electron will increase. And if the wavelength increase the energy will decreases due to: $E=hf$. B …
