        Phosphorus and carbon are dull, brittle solids that                SUMMARY

                                                           A nonmetal is an element that has no metallic
                                                          properties. Solid nonmetals are dull and brittle

                   There are two common forms
                  of phosphorus. The white form
                   is stored in a liquid because it
                     bursts into flames when
                        exposed to oxygen
