##### What exactly is a "nodal plane"- I don't even get what a node is!?
« on: September 08, 2009, 11:29:00 PM »
I know that a node is where the wavefunction is zero, so I guess if the wavefunction squared is also zero, it's just a region where the electron is unlikely to ever be found. But I still don't really get what a node is- why do they exist? Or should I just not think about it too much?

I certainly don't know what they mean by "nodal plane", though; this is how they refer to hybridization in my freshman chem book, but they don't use that term in my organic chem book and I don't really get what they mean.

Thanks!

Yes, a node is where the solution to Ψ2 (square of the wavefunction) is zero.  There is zero probability of finding an electron at a node.

Maybe start here, see if it helps:
