Why does each element have a different atomic spectroscopy? I think it was said in the lecture today but I didn't quite get it down. Thanks!

Hey! So, the atoms of each element all consist of electrons with unique arrangements. Their unique arrangement coincides with each individual electron having a different pattern of energy (which is released as a photon when an electron is excited and goes from a higher energy to a lower one). This distinct pattern of electron configuration/energy release leads to the variations in atomic spectra from element to element that we see. Hope this helps!

Because each element has a different number of protons, each element's nucleus has a different positive charge.
This variation in positive charge for each element causes the electrons in each element to be bound to the atom by a different amount of energy.
The slight differences in configuration caused by this differing energy means the gaps between electron levels in each element are different.
Since each element will only absorb/emit light of the exact energy corresponding to the gaps in its energy levels, each element has a different atomic spectrum.

wait so if every element has a unique spectroscopy then how do our problems all coincide with the same spectrums/ do we need to memorize the spectrum lines (Laymen series etc)???
