If uncertainty in momentum of electron is zero, the uncertainty in its position would be _ .
Correct answer: D. Infinite
- A. Less than zero
- B. More than zero
- C. One
- D. Infinite
Explanation
According to Heisenberg's uncertainty principle, the more precisely the momentum of an electron is known, the more uncertainty there is in its position, and vice versa. If the momentum of an electron is zero, it means that it is known with absolute certainty and hence, the position is infinitely uncertain. So,option D is correct.

About Quantum Numbers
Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
