In the atomic theory it states that all atoms of the same element are identical. in the 21st century, science knows this is incorrect because of the presence of:

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)
