Vedclass · Answer

(B) is correct: Heisenberg uncertainty principle applies to microscopic particles like electrons.$B$ is correct: The size of an orbital increases with an increase in the principal quantum number $(n)$. Since $n=3 > n=2$, the size of $3p_x$ is greater than $2p_x$.$C$ is incorrect: For multi-electron atoms, the energy of an orbital depends on both $n$ and $l$. For hydrogen-like species, energy depends on $Z^2$. Since $H$ $(Z=1)$ and $Li$ $(Z=3)$ have different atomic numbers, their $2s$ orbitals have different energies.$D$ is correct: The electronic configuration of $Cr$ $(Z=24)$ is an exception to the Aufbau principle, resulting in $[Ar] 3d^5 4s^1$ due to the extra stability of half-filled $d$-orbitals.

Laws	Statements
$(1)$ Hund's Rule	$(A)$ No two electrons in an atom can have the same set of all four quantum numbers.
$(2)$ Aufbau Principle	$(B)$ Half-filled and fully-filled orbitals have greater stability.
$(3)$ Pauli Exclusion Principle	$(C)$ Electrons prefer to remain unpaired in degenerate orbitals first.
$(4)$ Heisenberg's Uncertainty Principle	$(D)$ It is impossible to determine simultaneously the exact position and exact momentum of an electron.
	$(E)$ In the ground state of atoms,orbitals are filled in the order of increasing energy.
