A group is a column of elements in the periodic table with similar chemical properties. Learn about the modern and historical group names, numbers, and compositions, and see the table of elements by group.
A group is a vertical column in the Periodic Table, numbered or named according to the elements it contains. Learn how groups are used in chemistry, chemical engineering, and physics with examples and references.
A group is a vertical column of elements with the same number of valence electrons, while a period is a horizontal row of elements with the same number of electron shells. Learn about the 18 groups and 7 periods of the periodic table and their properties, trends, and exceptions.
Learn about the periodic table of the elements, the organized array of all the chemical elements in order of increasing atomic number. Find out how the elements are classified into groups, periods, and families based on their properties and atomic weights.
Learn how the periodic table is organized into periods, groups, and families based on the number of valence electrons and chemical properties. Find out the examples, characteristics, and color codes of each group and family of elements.
Learn how to read the periodic table by understanding the groups, periods, and families of elements. See examples of periodic trends, properties, and valence electrons for each group.
Learn how elements are grouped by their similar properties and reactivity in the periodic table. Find out the characteristics of each group, from metals and non-metals to noble gases and halogens, with examples and reactions.
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Learn the meaning of group in chemistry, as a column in the periodic table or a family of elements with similar properties. Compare different numbering systems and examples of groups.
