The primary basis upon which we divide the ingredients of the solar nebula into four categories (hydrogen/helium; hydrogen compound; rock; metal) is the temperatures at which various materials will condense from gaseous form to solid form. This process is also known as condensation sequence, where materials with the highest condensation temperature (e.g rock and metal) condensed and solidified closest to the Sun and those with lowest temperature, such as hydrogen and helium, remained gaseous farthest from the Sun.
