Group 2 or IIA Alkaline Earth Metals (Alkaline Earths) 2 valence electrons Metallic solids, harder than the alkali metals Shiny, lustrous, oxidize easily 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. The characteristics of the elements in these families are determined primarily by the number of electrons in the outer energy shell. In the periodic table of chemical elements, there is a group (also known as a family) is a column of elements. Lessons in Sodium and potassium are examples of elements in this family. Representative elements are known as such because the number of groups represents the number of electrons in their valence shell and the number of electrons in that shell tells us the maximum atomic valence that the element can have.

Examples of representative elements: Sodium (Na), Magnesium (Mg), Aluminium (A Silicon (Si). 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. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. There is no faster or easier way to learn about the representative elements. the modern periodic table consists of 7 periods ( horizontal rows ) , 18 groups ( vertical columns ) , the elements are arranged ascendingly according to their atomic numbers and the way to fill their atomic energy sublevels by electrons according to the aufbeau ( building-up ) principle , where each element has one electron more than the element for example Z=35. Topics covered include: The periodic table consists of organized, abbreviated letters and numbers, with representative elements being those in groups 1A-8A. The term earth is nothing more than an archaic word that refers to something that can be dissolved in acid. The group 5A elements are not so well known but are important to chemistry and the study of the sciences. The Transition Metals are the elements in those Groups within the middle of the Table. non metallic elements in periodic table. Most element symbols have two letters, the first is always capitalized and the second is lowercase, so the symbol for chlorine is Cl. Boron Group or Earth Metal Family of Elements. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. What are the elements in the representative element group? Periods have different lengths; the first period has only 2 elements (hydrogen and helium), while the second and third periods have 8 elements each. Non-representative elements include the transition elements, which have valence electrons in the s and d shells, and the lanthanide and actinide series, which have valence electrons in the s and f shells.
