Question

numbers of nodes present in 3d are _____?

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is C

2

We know,

Total number of angular nodes = l

$3d\Rightarrow n=3andl=2$

Therefore, angular nodes = 2

Number of radial nodes = n - l - 1

= 3 - 2 - 1 = 0

$\therefore$ Total number of nodes = 2

Or

Total number of nodes = n - 1

= 3 - 1 = 2
