* اتم کربن در متان: fc = 4 - 0 - (8÷2) = ۰* no۲ اتم نیتروژن در: fc = 5 - 2 - (6÷2) = ۰* no۲ اتم اکسیژن با پیوند دوگانه در: fc = 6 - 4 - (4÷2) = ۰* no۳- اتم نیتروژن در یون نیترات: fc = 5 - 0 - (8÷2) = +۱باید توجه داشته که جمع جبری تک تک بار قراردادی اتمها برابر با بار کلی مولکول خواهد بود و بر عکس.
examples:* carbon in methane: fc = 4 - 0 - (8÷2) = 0* nitrogen in no2−: fc = 5 - 2 - (6÷2) = 0* double bonded oxygen in no2−: fc = 6 - 4 - (4÷2) = 0* single bonded oxygen in no2−: fc = 6 - 6 - (2÷2) = -1an alternative method for assigning charge to an atom taking into account electronegativity is by oxidation number.
