d orbitals

Postby Jessica Li 4F » Fri Oct 18, 2019 3:24 pm

I know that the p orbitals can be written as px, py, and pz, but what about the d orbitals?
Also, for tests, will we have to be specific and write out the subscripts, or can we just write, for example in carbon, 1s22s22p2 instead of 1s2 2s2 2px?

Since d orbitals are present in a plane rather than along a line like p orbitals, we can use something like dxy to represent a d orbital that is in the xy plane. However, the lobes of the orbital aren't along the x and y axes, but rather in between the axes.
Hence, the dxz and the dyz orbitals also exist in a similar manner.
There is a dz^2 orbital that is found along the z axis and has a bit of a donut shape around its middle, as well as a dx^2y^2 orbital that lies directly along the x and the y axes.
