Question

The probability of finding an electron in an orbital is approximately:

• A. 95%
• B. 50%
• C. 60%
• D. 25%

Answer 1

The correct option is A 95%

The space in which there is maximum probability of finding an electron is termed as orbital. The probability of finding the electron at any point in space is never zero. Therefore, an orbital has no distinct size. An electron orbital is most commonly defined as the radius of the sphere that encloses 95% of the total electron probability.

Hence, the correct option is A.
