The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don't have a definite position, and direction of motion, at the same time!

Understanding the Uncertainty Principle
The uncertainty principle, formulated by Werner Heisenberg, is a fundamental concept in quantum mechanics that highlights the limitations of measuring certain pairs of physical properties.
Key Concept
- The principle asserts that there is a fundamental limit to the precision with which certain pairs of physical properties, known as complementary variables or canonically conjugate variables, can be known simultaneously.
Position and Momentum
- Specifically, the most commonly referenced pair is position and momentum.
- According to the uncertainty principle, if you measure the position of a particle, like an electron, very accurately, its momentum becomes highly uncertain, and vice versa.
Mathematical Representation
- The relationship is often expressed mathematically, indicating that the product of the uncertainties in position (Δx) and momentum (Δp) is always greater than or equal to a constant (h/4π).
- This means that the more precisely we know one quantity, the less precisely we can know the other.
Implications for Electrons
- This principle is crucial for understanding the behavior of electrons in atoms, as they do not have definite paths but rather exist in a cloud of probabilities.
- It challenges classical mechanics, where position and momentum could be known with arbitrary precision.
Conclusion
- Therefore, option ‘C’ correctly states that it is impossible to know the exact position and momentum of an electron simultaneously, emphasizing a core tenet of quantum mechanics and the inherent limitations of measurement at the quantum level.
