Question

What is the number of nodes in 3s orbita​

Answer 1

Answer:

The 3s orbital has two radial nodes separating three phases.

Answer 2

$2 nodes$

• The number of nodes is related to the principal quantum number, n. The ns orbital has (n-1) radial nodes, so the 3s-orbital has (3-1) = 2 nodes, as shown in the above plot
