This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.

Video Topics

As the n value of the subshell of the electron increases the distance between the nucleus and the electron also increases. This means that the as n increases the interaction between the proton and electrons decreases. Electrons in orbitals closer to the nucleus shield the nucleus from electrons further away. The effective nuclear charge, Zeff, that an electron feels depends on the actual nuclear charge, Z, and the screening ability of other electrons in the atom. This video helps to define the periodic tend of Zeff.
