Effective Nuclear Charge (Zeff) measures the force exerted onto an electron by the nucleus. 

Effective Nuclear Charge & Slater's Rules

Within any given atom there are electrons that experience both attractive and repulsive forces. 

Concept #1: Effective Nuclear Charge

Concept #2: Effective Nuclear Charge

Concept #3: Effective Nuclear Charge

Example #1: Using Slater’s Rules calculate the effective nuclear charge of a 3p electron in argon.  

Example #2: Using Slater’s Rules calculate the effective nuclear charge of the 4s electron in potassium.  

Example #3: Using Slater’s Rules calculate the effective nuclear charge of a 3d electron in bromine.
