The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, making … WebSuppose you have 10 gram of carbon. Now, it should be converted in terms of atoms. We know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole. Also, the Avogadro constant is 6.02 x 10 23. So, the conversion of carbon from grams to atoms is given by = 10(1/12)( 6.02 x 10 23) = 5.02 x 10 23 trump tower chicago parking garage
