WebA Periodic table to view elements in 3D. Hydrogen is the most common element in the universe, making up about 75% of its mass. WebThe periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons. Meanwhile, elements in the same period have the same number of occupied electron shells. In 1869 Russian chemist Dmitri Mendeleev ...
