NEET · Chemistry · STD 11 - 2. structure of atom
Which one is the wrong statement?
- A The uncertainty principle is \(\Delta E \times \Delta t \geq \frac{h}{4\pi}\)
- 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 \(2s-\) orbital is less than the energy of \(2p-\) orbital in case of hydrogen like atoms.
- D de-Broglie's wavelength is given by \(\lambda = \frac{h}{mv}\), where \(m =\) mass of the particle, \(v =\) group velocity of the particle.
