From Wikipedia, the free encyclopedia In the periodic table of the elements, each numbered column is a group. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.

Electronegativities generally decrease from top to bottom of a group. The highest electronegativity value is for fluorine. The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called groups) and columns (called periods) according to increasing atomic number. Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol.

Their name refers to the alkaline substances that form when these elements react with water. The most common of these elements are sodium and potassium. 89 Ac Actinium (227) 90 Th Thorium 232.04. 91 Pa Protactinium 231.04.
