The element that has the same number of valence electrons as bromine (Br), is chlorine (Cl).
In the periodic table, elements in the same group have the same valence electrons. These valence electrons are the electrons found at the outermost shell of an atom.
Elements in the same group in the periodic table share similar chemical properties. For Example;
- group 1 elements are called Alkali metals and they have 1 valence electron in their outermost shell, they include lithium, sodium, potassium, rubidium, caesium, and francium. They are the most reactive metals.
- group 7 elements have 7 valence electron in their outmost shell, they include Fluorine (F), chlorine (Cl), Bromine (Br), Iodine(I), Astatine(As).
Thus, the element that has the same number of valence electrons as bromine (Br), is chlorine (Cl).
