Ok but how many valence electrons does an atom : They share one electron 3. Name the orbitals that are occupied.How many electrons are needed to fill the valence shell? Name the orbitals that are occupied.How many electrons are needed to fill the valence shell? Valence electrons are those electrons which are present in the outermost shell of an atom. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals. 9 + 1 = 10. The outer electrons are ineffective at nuclear shielding, and experience a high effective nuclear charge of 9 − 2 = 7; this affects the atom's physical properties. Problem7 How many valence electrons do Fluorine have? He who owns the information, owns the world – said V.Cherchill. Now I am going to show you how many valence electrons fluorine have in just 5 steps. 1. How many electrons does fluorine have? How many valence electrons does it have? Q: Energy level III can hold a maximum of 18 electrons. Therefore, the number of electrons in an atom of fluorine are 9.
