Nodes on the Midterm?

Postby Maria1E » Wed Nov 08, 2017 7:14 pm

Do we need to know anything about nodes for the midterm (i.e. angular nodes, radial nodes)? This topic was briefly mentioned in my discussion section but I wasn't sure if we are going to be tested on it or if it's just for our own knowledge.

Not sure about the types of nodes, but in one of the review sessions I remember one of the TAs saying something about just knowing what the electron density around a node is.

Hi, my TA told our discussion that we only need to know that S does not have any nodes but P does have a node, which is an area of zero electron density. He said that is all we need to know for this class.

All I was told about nodes is that angular nodes equal n-l-1 and radial nodes equal n-l. Is this right and there is more I need to know about them other than there is 0 electron density in that region?

I think the point of the explanation of nodes was only to show the e- distribution of atoms (e.g. s orbitals have no nodal plane so it has symmetric e- distribution), and that might help in explaining something on the final
