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. WebJan 7, 2024 · In the first period, only the 1 s sublevel is being filled. Since all orbitals can hold two electrons, the entire first period consists of just two elements. In the second period, the 2 s sublevel, with two electrons, and the 2 p sublevel, with six electrons, are being filled. Consequently, the second period contains eight elements.
