WebThere are over 100 known atoms — one for each of the known elements. On the periodic table, elements are listed in order of increasing atomic number. Elements in the same row are in the same period. This means they have similar physical properties, such as how well they bend or conduct electricity. Elements in the same column are in the same group. WebThe 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).
