It should be predicted that why the formula N a 2 C l do not exist. Concept introduction: The main group elements form chemical compounds in which the central atom has highest oxidation number. The highest oxidation number is always equal to the group number that the element has in the periodic table. Thus, the oxidation number is determined by the position of the element in the periodic table. These elements also form compounds in the other lower oxidation numbers apart from the highest oxidation number. These other oxidation numbers are as per the electronic configuration of the element and is determined by the number of electrons in the outer shell of each element. The correct formula has the valid oxidation number of the central element and the formula which do not satisfy this criteria is incorrect
