Question

effective nuclear charge for flurine

​

Answer 1

Explanation:

The more shielding, the further the valence shell can spread out and the bigger atoms will be. The effective nuclear charge is the net positive charge experienced by valence electrons. It can be approximated by the equation: Zeff = Z – S, where Z is the atomic number and S is the number of shielding electrons.

Answer 2

Answer:

Finally subtract the value of S from Z to find the value of effective nuclear charge, Zeff. For example, Us the Lithium atom, then Z =3 (atomic number) and S = 1.7. ... So, the value of effective nuclear charge of 2s electron in Lithium atom is 1.3.
