In this numbering system, group 1A is group 1; group 2A is group 2; the halogens (7A) are group 17; and the noble gases (8A) are group 18. You will come across periodic tables with both numbering systems.

The elements of the periodic table in groups 1A to 8A are called the main-group elements. They are sometimes also called the representative elements and they are the most abundant in the universe. Some of the main group elements have common names, such as the alkali metals (1A), the alkaline earths (2A), the halogens (7A) and the noble gases (8A).

According to the Aufbau principle , the electrons of an atom occupy quantum levels or orbitals starting from the lowest energy level, and proceeding to the highest, with each orbital holding a maximum of two paired electrons (opposite spins). Periodic Table Names and Symbols Groups 1A - 2A, 7A - 8A.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends.

1A is the Alkali Metals and 2A is the Alkaline Earth Metals 3A through 7A are all subsets of Transition Metals with no special names for themselves. The elements of the periodic table in groups 1A to 8A are called the main-group elements. They are sometimes also called the representative elements and they are the most abundant in the universe.
