The periodic table is divided into eight main groups. These are the alkali metals, alkaline earth metals, transition metals, halogens, noble gases, lanthanides, actinides, and nonmetals. Alkali metals are the elements located in Group 1 of the periodic table. They are soft, silvery-white metals that react vigorously with water. Alkaline earth metals are the elements in Group 2. They are heavy, solid metals that are less reactive than alkali metals.

Group: A vertical column of elements on the periodic table which have similar chemical properties. Groups are also known as families. Period: A horizontal row of elements on the periodic table which have similar electron configurations. Periodic Table: A chart or table of elements arranged in order of their atomic number, usually in rows and columns, showing the chemical elements, their atomic number and symbol, and their atomic weight.

The first person to develop a periodic table was a Russian chemist named Dmitri Mendeleev in 1869. The Groups on the periodic table are numbered from 1-18, with Group 1 being alkali metals, Group 2 being alkaline earth metals, Groups 3-12 being transition metals, and Groups 13-18 being the other metals, non-metals, and halogens. The Groups on the periodic table are also known as families, and each family has similar characteristics that make them unique from other elements.

Before the periodic table was developed, scientists used to organize elements into groups based on their physical properties like color, luster and hardness. The elements on the periodic table are organized in order of increasing atomic number, not alphabetically. The most abundant element in the universe is hydrogen, but it is not the most abundant element on Earth, which is oxygen.
