When the atomic number increases, the element have different properties. A new row begins when chemical properties repeat. The periodic table codifies the energy levels in periods, the rows on the table. The simplest atoms, hydrogen and helium, are found in row 1, or the first period. These atoms have electrons occupying the energy level n=1. Moving down, row 2, or period 2, contains the elements Li (lithium) through Ne (neon).
