What group of elements has seven valence electrons?
The name of the family is the Halogen family.
How many valence electronss does each fluorine atom have?
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
How many valence electrons are in an atom of bromine?
