Question

The Heisenbergs Uncertainty principle states that:

• A. no two electrons in the same atom can have the same set four quantum numbers
• B. two atoms of the same element must have the same number of protons
• C. it is impossible to determine accurately both the position and momentum of an electron simultaneously
• D. electrons of atoms in their ground states enter energetically equivalent sets of orbitals singly before they pair up in any orbital of the set

Answer 1

Answer: (C)

it is impossible to determine accurately both the position and momentum of an electron simultaneously

Heisengbergs Uncertainly Principle :

According to this statement we can not measure velocity and position at the same time of a election (object).

so, C is correct.
