Structure Of Atom Ques 63
63. The number of spherical nodes in $3 p$ orbitals are
[1988]
(a) one
(b) three
(c) none
(d) two
Show Answer
Answer:
Correct Answer: 63.(a)
Solution:
- (a) No. of radial nodes in $3 p$-orbital
$=(n-l-1)$
[for $p$ ortbital $l=1$ ]
$=3-1-1=1$
There are two types of nodes, angular nodes and radial notes. Angular nodes are typically flat plane. The quantum number $l$ determines the number of angular nodes in an orbital. Radial nodes are spheres that occurs as the principal quantum number increases. Total nodes of an orbital is the sum of angular and radial nodes which is given by $N=n-l-1$
