JEE Advanced 2024 Chemistry question on Atomic Structure

1. A.
   Uncertainty principle rules out the existence of definite paths for electrons.
2. B.
   The energy of an electron in $2s$ orbital of an atom is lower than the energy of an electron that is infinitely far away from the nucleus.
3. C.
   According to Bohr's model, the most negative energy value for an electron is given by $n = 1$, which corresponds to the most stable orbit.
4. D.
   According to Bohr's model, the magnitude of velocity of electrons increases with increase in values of $n$.
