Question

hii guys what is zeff?...... explain in brief.....♥♥​

Answer 1

Answer:

Effective nuclear charge – the attractive positive charge of nuclear protons acting on valence electrons. The effective nuclear charge is always less than the total number of protons present in a nucleus due to shielding effect.

Answer 2

Zeff is a measure of how strongly any given electron is actually held in place within an atom, and it varies from one electron to another within an atom. By comparing the Zeff of any electron to the Z of the nucleus, you can also get a measure of exactly how shielded that electron is.
