Their name is the same as the symbol for a nonmetallic element that has red and white allotropes and is used in matches.
These things can be partially described by spherical harmonics with L-index 1. They have a single nodal plane and are bilobate. In an aufbau table, one of these things is the third thing that is added-to. In hydrogen, electronic transitions down to them lie in the visible range and are named for Balmer. In methane, these orbitals on the carbon atom are given the exponent "3" when hybridized to form a tetrahedral geometry. Their name is the same as the symbol for a nonmetallic element that has red and white allotropes and is used in matches. For 10 points, name these things that are higher in energy than s orbitals and share a name with the chemical symbol for phosphorus.
