Balmer/Lyman Series

Postby Luke_Lucido_3B » Thu Oct 06, 2016 10:05 pm

Can someone explain to me again why the chart goes up from a negative towards 0 when changing energy levels?

When Bohr's model of the H atom was established, free electrons (not part of the atom) were considered to have 0 energy. Electrons closer to the nucleus have less energy than those that are farther away. Since free electrons are the farthest away (n=∞) and have 0 energy then in comparison electrons closer to the nucleus (n=1,2,3,4...∞) must have lower energy so they are given negative energy values.

Can somebody explain the concept of the balmer/lyman series and why the balmer series covers the visible region and the lyman series covers the ultraviolet region? Thank you. :)
