Problem: How many valence electrons are in fluorine atom?

FREE Expert Solution

To determine the number of valence electrons of an atom, let’s first write its electron configuration.

Ground-state means that Carbon is in its lowest energy form (not in excited state). Carbon also has no charge (neutral element) which means that no electrons are removed or added in the atom.

Neutral element:       Atomic number = # protons = # of electrons

Fluorine:

▪ Atomic number = 9

▪ # of electrons = 9 e-
