← ScienceWhich outcome arises when an electron's location is not constrained?
A)Increased uncertainty in electron momentum✓
B)Decreased probability density at nucleus
C)Increased ionization energy requirement
D)Decreased electron orbital angular momentum
💡 Explanation
If an electron's position is known imprecisely, the Heisenberg Uncertainty Principle dictates increased variance in momentum measurement, because it's founded on complementary variables. Therefore, momentum uncertainty increases, rather than a change in electron density or energy, under these conditions.
