I mean...that..when electron is excited..it gains energy and moves to higher energy level. But this transition is done only when the total required energy is gained or its in between the two shells...as it slowly gains energy....and ultimately reaches the destination shell when the required energy is obtained.>??!!

Has mercury been banned in thermometers, including cooking thermometers? If so, when?
How do you know if your thermometer has mercury?
