Px py and pz

Postby emmajanibekyan_4I » Sat Oct 22, 2016 9:49 pm

I'm confused as to what these represent and how we use them.

The 'p' refers to the p-block of the periodic table, with that specific type of orbital. As far as I understand, x, y, and z represent the different orientations that a p-orbital can have. I've included a picture that represents the orientations and where their nodes fall.

I've seen this when writing out the hybridizations of certain bonds, is there any other instance where we would use them?

We generally only use this when determining hybridizations.

The x in Px stands for the p orbital on the x axis. Likewise for the y in Py and the z in Pz. You use them in hybridization, but the notation just helps you to differentiate between the three orbitals and where they lie.
