Explanation A chemical species is given by A M B N ,where A , B are the symbols of the elements and M , N are the number of atoms of the same element that are present in the same molecule (atomicity). a. In the question diagram,blue spheres represent nitrogen atoms while purple spheres represent iodine atoms.So, for nitrogen atoms A = N and M = 2 as two nitrogen atoms are present in 1 N 2 molecule.So, formula = N 2 . Similarly,for iodine, A = I , M = 2 . So, formula = I 2 .So, formula of reactants = N 2 , I 2 . In given product picture, there are 4 molecules and each contains 1 nitrogen and 2 iodine atoms. So, A = N , B = I and M = 1 , N = 3 . So, formula of product is N I 3 . b. General rule for a balanced equation is that the number of individual atoms in the reactant (left hand side) side must be equal to the number of individual atoms in the product side (right hand side)
