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). There also is a B group of transition metals that falls in between the 2A and 3A main groups.

As we have seen, elements in a given group possess general similarities. However, trends also exist within each group. In this section we use the periodic table and our knowledge of electron configurations to examine the chemistry of the alkali metals and alkaline earth metals. FIGURE 7.18 Elemental The periodic table is structured so that elements with the same pattern of outer-shell (valence) electron configuration are arranged in columns.

Our current periodic table lists 109 elements. Metals include the areas shaded light blue and include the families 1A & 2A. p-block is group 3A to 8A. You can predict the energy level of an element's valence electrons using the element's period number in the periodic table.

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). The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges. •. 2016-08-18 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.The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

There are 112 elements although elements 110-112 are as yet unnamed. These 112 elements are organized in the periodic table: The modern chemical symbols were introduced by Berzelius. Rows of elements are called "periods" and columns of elements are called "groups" (1A, 2A 3B etc.). Mendeleev published his periodic table in 1869, along with references to groups of families of elements, and rows or periods of his periodic table. At the same time, Hinrichs wrote that simple lines could be drawn on a periodic table in order to delimit properties of interest, such as elements having metallic lustre (in contrast to those not having such lustre).
