Lightbulb Is there any change in mass as the electron changes energy levels.

Does anything happen to the electron, as it changes energy levels, does its mass increase, or decrease, or velocity speed up, or slow down.?
The electron will speed up when its away from the nucleus, when its in a higher shell like shell level 3.
But is there anything like a visible sign that the electron has changed energy levels, (energy requirement to EM waves to absorb, and emission).
The electron is a mysterious particle, it seems to give no indication of its energy change in electron volts, but it does change all the time as atoms form covalent bonds, and become molecules, and as it moves away from the nucleus, to higher shell levels, in the absorption, and emission spectrum.
It is impossible to determine the location of any electron so this is a difficult question to ask.
I am grateful for your help, anything helps even a few words.
