I have studied this in my chapter atomic structure that when an electron changes its orbit from lower energy to higher energy state , it does not state in my book that it moves there but that it disappears.It just kind of reaches that orbit without crossing the path.We don’t know whether it moves there or not.
So , I also read about the fundamental properties of electron in which it said that when an electron moves or is in motion , it’s mass changes.
If we see , We know that electron only absorbs certain wavelength of light. If we can find that when it changes its orbit , if it’s mass decreased or not during that interval.Is it that we can find that whether electron moves and changes orbit or it just disappears kind of.
Yes , I am only talking electron in an hydrogen atom here.
Please do give your answer in reference to other atoms if it is helpful.
