The element with 15 protons, 16 neutrons, and 15 electrons is phosphorus.
Phosphorus has an atomic number of 15, which means it has 15 protons and, in a neutral atom, also 15 electrons. The number of neutrons can vary to create isotopes, and in this case, having 16 neutrons gives this isotope of phosphorus a mass number of 31 (15 protons + 16 neutrons).
