Question

What is the zeff for for fluorine

Answer 1

Answer:

Effective nuclear charge (Zeff) is a useful tool for understanding periodicity. Fluorine: Zeff = 9 – 2 = 7+. So: when we go down a period the effective nuclear charge increases. Example: atomic radius of C vs F. Zeff of C is 4+, and C has 4 valence electrons.

Answer 2

Zeff for for fluorine is 7

Explanation:

• Zeff is the effective nuclear charge.
• It is the positive charge which is attracting an electron in an atom.
• The energy of the orbitals depends on Zeff.
• Zeff =Z (actual nuclear chargeof the ion)-Z core (core electrons in the nucleus.
• The core of the electrons are in the subshell between the electrons and its nucleus.
• Effective nuclear charge is the net positive charge which is experienced by the valence electrons.
• Zeff=Z-S
• where Z is the atomic number and S is the number of shielding electrons

Zeff for fluorine :-

Z=Atomic number of fluorine is 9

S=core electron is 2

Zeff=9-2 that is 7

Zeff for for fluorine is 7
