The main group elements are the chemical elements belonging to the s-block and p-block on the periodic table. These are elements in group 1 and group 2 (s-block) and groups 13 through 18 (p-block). In older IUPAC group numbering systems, the main group elements are groups IA, IIA, and IIIA to VIIIA.
In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
Main Group Elements - The elements in groups 1 and 2, as well as those numbered 13 to 18, are referred to as main group elements or representative elements. In the periodic table, groups 1 and 2 represent the s-block, and groups 13 to 18 represent the p-block.
What are the main group elements? The main group elements are those in the s and p blocks of the periodic table, as shown in Figure 8.2.1. Figure 8.2.1. Location of the main group elements in the periodic table. 1. Why should anyone care about the main group elements?
The main group elements of the periodic table are the elements belonging to s- and p-blocks. These include the Group 1 and 2 elements (s-block), except hydrogen, and Group 13 to 18 elements (p-block) [1-4].
Below are the different groups of the periodic table [1-7]. A family consists of elements having similar characteristics. The elements of a family may belong to the same group or spread across several groups. Each family of elements is color coded to understand their position in the periodic table. There are ten families.
In chemistry and physics, the main group elements are any of the chemical elements belonging to the s and p blocks of the periodic table. The s-block elements are group 1 ( alkali metals ) and group 2 ( alkaline earth metals ).
In chemistry, the representative elements are the elements with atoms filling s and p electron orbitals. Another name for the representative elements is the main group elements. The representative elements are groups 1 and 2 and group 13-17 on the periodic table.
In this tutorial you will be introduced to the main group elements in chemistry and physics, and why they are considered the main group elements. The main group elements, also known as the representative elements, consist of elements belonging to the s-block and p-block of the periodic table and are most abundant on earth and space.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number. The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements.
