How many valence electrons do br have

WebValence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds. If the valence shell of an element is full, such as with a noble gas, then the element does not want to gain or lose an electron. For example, alkali metals, which all have a valency of ...
