Coulomb's Law

Postby Tamera Scott 1G » Wed Oct 24, 2018 3:10 pm

I'm not sure if we have went over Coulomb's law yet, but what exactly does it state?

The gist of it is that the electrostatic potential energy (basically attractive force) is proportional to q1*q2/r where q1 and q2 are the charges (in the context of chem these are the charges of protons and electrons) and r is the distance between the charges. This explains why it is easier to remove electrons higher energy electrons because they are the furthest away from the nucleus (they also "feel" less of an attraction because of shielding from inner electrons) and also explains the other trends in the periodic table we discussed today in lecture (ionization energy, atomic radius).
