Question

Identify the CORRECT statement

• A. Quantum numbers $(n,I,m,s)$ are obtained arbitrarily
• B. All the Quantum numbers $(n,I,m,s)$ for any pair of electrons in an atom can be identical under special circumstance
• C. All the Quantum numbers $(n,I,m,s)$ for any pair of electrons in an atom cannot be identical under special circumstance
• D. All the quantum numbers $(n,I,m,s)$ are required to describe an electron of an atom completely

Answer 1

Answer: (D)

All the quantum numbers $(n,I,m,s)$ are required to describe an electron of an atom completely

Answer 2

All the quantum numbers $(n, I, m, s)$ are required to describe an electron of an atom completely.
e.g., $n$ describes the position and energy of the electron in an orbit or shell. $I$ is used to describe
subshell and the shaple of the orbital occupied by the electron. $m$ describes the preferred orientation of orbitals in space. s describes the spining of an electron on its axis.
