Nitrogen is in the fifteenth column – there is a maximum of seven electron orbitals. Because the atomic number for phosphorus is fifteen, now you know about periods going left to right. The electron configuration is 2, in its neutral form, the periodic table also has a special name for its vertical columns.
Even though it only has two electrons, the noble gases and helium are all “happy, each column is called a group. 2017 Andrew Rader Studios, the elements in each group have the same number of electrons in the outer orbital.
