Periodic Table Geography

The horizontal rows of the periodic table are called PERIODS.

The elements in any group of the periodic table have similar physical and chemical properties! The vertical columns of the periodic table are called GROUPS, or FAMILIES.

Periodic Law When elements are arranged in order of increasing atomic number, there is a periodic pattern in their physical and chemical properties.

Alkali Metals

Alkaline Earth Metals

Transition Metals

InnerTransition Metals These elements are also called the rare-earth elements. InnerTransition Metals

Halogens

Noble Gases

Electrons are confined to specific regions of space called principal energy levels or shells. Shells are divided into subshells designated by the letters s, p, d, and f. Within these subshells, electrons are grouped in orbitals An orbital is a region of space and can hold two electrons.

The s and p block elements are called REPRESENTATIVE ELEMENTS.
