How elements on the periodic table
WebThe periodic table as we use it today was created by Dmitri Mendeleev in 1869. However, Mendeleev’s table was not the first attempt at bringing order to the elements. As early as 1789, chemists like Antione Lavoisier attempted to group the known elements scientifically. Lavoisier grouped them as gases, metals, nonmetals, and earths. WebIf you can locate an element on the Periodic Table, you can use the element's position to figure out the energy level of the element's valence electrons. A period is a horizontal row of elements on the periodic table. For example, the elements sodium ( Na) and magnesium ( Mg) are both in period 3.
