why do electrons in a higher energy level have more energyWatch
Another way to explain is that electron's further from the nucleus are held more weakly by the nucleus, and so can be removed by spending less energy. Hence we say they have higher energy.
(BTW higher energy is kinetic energy)
I don't understand why electrons have more energy if they are at a higher energy level
I also think it has something to do with electrons in higher levels being further away from the nucleus so therefore needing more energy for... something? But honestly don't know where to go with that. Someone else needs to take over lool
so a simple way to explain it is it's at a higher energy level as it's electron in p requires more energy to be further away from the nucleus ( is this to reduce attraction)
but if this is the case why does si which has a 3p orbital aswell have a higher ionisation energy then mg?
