Calculate the total number of angular nodes and radial nodes present in 4p and 4d orbitals.

Answer»

Solution :For 4p orbital : NUMBER of ANGULAR nodes = l
For 4p orbital l=1
`therefore` Number of angular nodes =1
Number of RADIAL nodes = n-l-1
`=4-1-1`
=2
`therefore` TOTAL number of nodes = n-1=4-1=3
1 angular node and 2 radial nodes.
For 4d orbital : Number of angular nodes = l
For 4 d orbitall=2
`therefore ` Number of angular nodes = 2
Number of radial nodes = n-l-1
`=4-2-1 `
=1
`therefore` Total number of nodes = n-1=4-1=3
1 radial nodes adn 2 angular node.
