Answer Q.31, Q.32 and Q.33 by appropriately matching the information given in the three columns of the following table
The wave function, ψn,l,ml s a mathematical function whose value depends upon spherical polar coordinates (r,θ,ϕ) ofthe electron and characterized by the quantum numbers n,l and ml Here r is distance from nucleus, θ is colatitude and ϕ is azimuth. In the mathematical functions given in the Table, Z is atomic number and a0 is Bohr radius
