For example halogens: F, Cl, Br, I, At.
Fluorine has 7 valence electrons.
Iodine has 7 valence electrons. It is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
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
one valence electron

neutrons
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.
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
