NEET Solved Paper 2017 Question 17
Question: Which one is the wrong statement?
Options:
A) The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms
B) de-Broglie’s wavelength is given by $ \lambda =\frac{h}{mv}, $ where m = mass of the particle, v = group velocity of the particle
C) The uncertainty principle is $ \Delta E\times \Delta t\ge \frac{h}{4\pi } $
D) Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement
Show Answer
Answer:
