Question

Name and draw the orbital with have donut shape?

Answer 1

Answer:

I hope that's it...... and the name is dz2

Answer 2

Name of the orbital is dz2

1. dz2 is conventionally regarded as a linear combination of two others, the (dz2–y2) and (dz2–x2) .
2. Thus these latter two orbitals have no independent existence, but the (dz2) can be thought of as having the average properties of the two.
3. Therefore since both have high electron density along the z axis, the (dz2) orbital has a large fraction of its electron density concentrated along the same axis.
4. Also, since one of the component wave functions (dz2–y2 ) has lobes along the y-axis and the other (dz2–x2) along the x-axis, the resultant (dz2) orbital has a torus of electron density in the xy plane.
5. The xy component which is often referred to as a ‘doughnut’ (or) a ‘collar’, is frequently neglected in pictorial representations, especially when an attempt is being made to portray all five d-orbitals simultaneously.
