For example halogens: F, Cl, Br, I, At.
Iodine has 7 valence electrons like the other halogens.
Fluorine has 7 valence electrons, (9 altogether) and ten neutrons.
The element chlorine has seven electrons in its valence shell.
I believe there is 8 electrons in the outer valence
neutrons
one valence electron

The order is: Iodine (7 valence electrons) Carbon (4 valence electrons) Calcium (2 valence electrons) Sodium (1 valence electron)
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
Boron has 3 valence electrons.Boron has 3 valence electrons.
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
