It has a valence of 1. Usually it’s oxidation state is +1, but it can lose the electron and have a valence of -1. The most stable oxidation state is one that fills or half …

WebA chlorine atom (Group VIIA) has seven valence electrons and each oxygen atom (Group VIA) has six valence electrons. Because the chlorate ion has a charge of -1, this ion contains one more Thus, the ClO3-ion has a total of 26 valence electrons. ClO3-: 7 + 3(6) + 1 = 26 The second step in this process involves deciding which atoms The electrons that determine valence – how an atom reacts chemically – are those with the highest energy. For a main-group element, the valence electrons are defined as those electrons residing in the electronic shell of highest principal quantum number n. Thus, the number of valence electrons that it may have depends on the electron configur…
