For which orbital is the probability density of finding an electron strictly zero everywhere along t — Atomic Structure Chemistry Question

💡 Solution & Explanation

The lobes of planar $d$ orbitals like $d_{xy}$, $d_{yz}$, $d_{zx}$ lie exactly *between* the respective coordinate axes. Therefore, their electron density is exactly zero directly along the principal $x$, $y$, and $z$ axes (these axes reside in the nodal planes).
