The p-block elements are groups 13-18 (basic metals, metalloids, nonmetals, halogens, and noble gases). The s-block elements are group 1 ( alkali metals) and group 2 ( alkaline earth metals ). It exists in numerous forms, the most common of which is amorphous boron, a black powder that is unreactive to oxygen, water, acids, and alkalis. 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. You can effortlessly find every single detail about the elements from this single Interactive Periodic table. Boron, a chemical element with the symbol B is semimetal of main Group 13 (IIIa, or boron group) of the periodic table with the atomic number 5. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ).

Free Gift for you: Interactive Periodic Table In this way, the elements of the same group show similar chemical properties and they also have the same number of valence electrons. They are soft and can be cut easily with a kitchen knife.Īlso all the elements of group 1 have one valence electron.Īll the elements of group 18 are chemically inert (that means they do not easily react with other elements).Īnd all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell). The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.Īll the elements of group 1 are highly reactive to water. There are total 18 vertical columns on periodic table. Groups are the vertical columns on the periodic table. The elements included in Noble gases group are įor detailed information on noble gases, read the main article on Noble gases of periodic table. Noble gases group is the last group (group 18) on the periodic table.
