Question

Probability of finding electron in YZ plane for \(p_x\) orbital is:

• A. \(100%\)
• B. \(0%\)
• C. \(90%\)
• D. \(95%\)

Hint:

For \(p\)-orbitals:
Each \(p\)-orbital has one nodal plane
The nodal plane always passes through the nucleus
Probability of finding electron in a nodal plane is zero

Answer 1

The Correct Option is B

Step 1: The \(p_x\) orbital is oriented along the \(x\)-axis.
Step 2: For a \(p_x\) orbital, the YZ plane (where \(x = 0\)) is a nodal plane.
Step 3: In a nodal plane, the wave function \(\psi = 0\), hence the probability density: \[ |\psi|^2 = 0 \]
Step 4: Therefore, the probability of finding an electron in the YZ plane for a \(p_x\) orbital is: \[ \boxed{0%} \]
