Highest energy level

Postby Isabel Day 1D » Sun Nov 03, 2019 4:48 pm

Page 31 of the textbook explains how the highest energy level is 0, but I don't understand what this means. If 0 is the point when the electron is escaping from the nucleus, how could this be the highest energy level?

The highest energy level is told to be zero because this is the point where the electron is completely removed from the atom and no longer experiences any pull force from the atom. You can see this as an energy level that takes an infinitely large number such as 1*10^999, which if you insert it into the energy formula E=-hr/n^2 would yield a result of 0. All the energy levels below it has a negative sign and increase in magnitude and decrease in energy because of the negative sign. An energy level of 1 will have the largest negative number, which means the lowest energy.
