Which one is the wrong statement?
A
The uncertainty principle is 
B
Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement.
C
The energy of 
‐orbital is less than the energy of 
‐orbital in case of hydrogen like atoms.
‐orbital is less than the energy of ‐orbital in case of hydrogen like atoms.
D
de‐Broglie’s wavelength is given by 
, where 
mass of the particle, 
group velocity of the particle
, where mass of the particle, group velocity of the particle
Text Solution
Verified by ExpertsThe correct answer is:
C
In case of hydrogen like atoms, energy depends on the principal quantum number only. Hence, 
‐ orbital will have energy equal to 
‐ orbital.
