Question

173. Wave function of an orbital is plotted against the distance from nucleus. The graphical
representation is of:
->
(a) is
(b) 2s
(c) 3s
(d) 2p​

Answer 1

The wave function of an orbital is plotted against the distance from the nucleus. The graphical  representation is of Option (c) 3s.

• Nodes present in the given graph = 2
• The electron density in an orbit = 0
• Number of nodes = n - 1

• (a) 1s
• = n - 1
• = 1 - 1
• = 0

• (b) 2s
• = n - 1
• = 2 - 1
• = 1

• (c) 3s
• = n - 1
• = 3 - 1
• = 2

• (d) 2p
• = n - 1
• = 2 - 1
• = 1
