Coulombic potential energy

Postby Isabel Day 1D » Sat Nov 02, 2019 10:28 pm

1E.3 asks (a) Write an expression for the total coulomb potential energy for a lithium atom. (b) What does each individual term represent?

I'm not sure how to answer this question because I don't understand the coulomb potential energy expression. The textbook expression looks different than the one we talked about in class, and I'm confused about when to use both.

in the book it says, "the total Coulomb potential energy V(r) is the sum of the individual coulombic attractions and repulsions." Hope this helps.

Is this something we need to know for the midterm?

Will we have to use this equation on the final or simply know the concept behind it?
