Answer:
The effective nuclear charge decreases with increase in azimuthal quantum number.
Explanation:
The effective nuclear charge can be calculated with the help of coulomb’s law. The effective nuclear charge is the charge experienced by the outer shell electron. It is always a positive value calculated by deducting the number of inner shell electrons from total number of protons in the nucleus. It is a net positive charge of the nucleus. The core charge decreases from left to right in the periodic table.
For example, oxygen (element 16) has electronic configuration 1s2 2s2 2p6 3s2 3p4. It has 16 protons and 10 inner shell electrons because of this core/ effective nuclear charge of oxygen would be +4.
