Question

the angular part of wave fraction for 2pz orbital is
​

Answer 1

Explanation:

The angular wave function Y1,0(θ,ϕ)=cosθ only depends on θ. Below, the angular wavefunction shown with a node at θ=π/2. As in the case of the s orbitals, the actual 3-dimensional p orbital shape is obtained by rotating the 2-dimensional cross-sections about the axis of symmetry, which is shown as a blue dashed line
