WebbPeriodic Table of the Elements. The modern periodic table has been almost 300 years in the making. Early efforts to group elements produced the tables of Geoffroy (1718) and Lavoisier (1787). The atomic theory formulated by Dalton in the early 1800s provided chemists with a solid basis to classify elements, and the theory Webb1.85. Beryllium. Be. 4.

WebbThe 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).
