The bromine atom possesses 35 electrons....

The bromine atom possesses 35 electrons. It contains 6 electrons in '2 p' orbital, 6 electrons in '3 p' orbital and 5 electrons in '4 p' orbital. Which of these electrons experiences the lowest effective nuclear charge?

Text Solution

Verified by Experts

As we go away from the nùcleus, effective nuclear pull goes on decreasing. Hence electrons present in 4p orbital experience the lowest effective nuclear charge.
