/sci/, how many electrons can fit into each energy level of an atom? I'm getting contradicting information from different websites, such as these two http://www.qacps.k12.md.us/qhs/teachers/WeedonD/atoms%20page%208.htm http://education.jlab.org/qa/electron_number.html What's going on here?

>>	Anonymous Mon Jul 22 12:02:03 2013 No.5917358 You're confusing shells and energy levels. The electrons in a higher shell do not necessarily have higher energy. Go to Wikipedia first: https://en.wikipedia.org/wiki/Electron_configuration

The problem is that electrons don't just fill from the innermost level upwards. Due to the varying amounts by which each electron blocks the other electrons from the nucleus' positive charge ('shielding'), the simple number of electrons in each shell isn't a very useful concept.

But the answer to your question is 2n^2 (2, 8, 18, 32, 50...).

>>	Anonymous Tue Jul 23 09:31:20 2013 No.5919616 Not OP, but can somebody explain why nodes between orbitals exist? I know it separates energy levels, is it just a separation between probable locations of electrons in a particular state?
