What is effective nuclear charge and what it represents
Answers
Answer:
Explanation: The effective nuclear charge (often symbolized as Zeff or Z*) is the net positive charge experienced by an electron in a multi-electron atom. The term “effective” is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge. It is an approximate magnitude of shielding effect or screening effect of an electron in multi-electron system
The effective nuclear charge on an electron is given by the following equation:
Zeff = Z – S
where Z is the number of protons in the nucleus (atomic number), and S is the number of electrons between the nucleus and the electron in question (the number of non-valence electrons).
