The periodic table of elements developed as scientists tried to classify elements. It arranges them in an order in which similar elements are grouped together. The periodic table is so named because of the regularly repeating patterns in the properties of elements. The modern periodic table was formed by a Russian scientist called Mendeleev in ...

The tendency to form expanded valence structures begins in the 3rd period of the periodic table because these central atoms make use of vacant 3d orbitals in their bonding. The tendency increases moving left-to-right because the energies of orbitals decreases, making those vacant orbitals more attractive to bonding electrons.

A period in chemistry is a complete row of the periodic table. The term period is inclusive of all elements between the ns1 position and the np6 position regardless of sublevel. (I.e., the 4th period contains elements in the 4s, 3d, and 4p sublevels.) A . group. in chemistry is a column of the periodic table.
