nonmetals in period 2

Non metals have s and p valence electrons, so they have 2 in s orbitals and up to 6 in p orbitals. Some of the other nonmetals are flammable (Hydrogen, Carbon, Phosphorus and Sulfur). This may best be explained by the facts that the These elements have similar chemical properties that differ from the elements considered metals. Ungraded .
