You can effortlessly find every single detail about the elements from this single Interactive Periodic table. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). Free Gift for you: Interactive Periodic Table For example, most noble gases have names ending with -on, while most. Discover videos related to periodic table group names on TikTok. The names of some elements indicate their element group. If there is a second letter, it is lowercase. Each element has a symbol, which is one or two letters. In this way, the elements of the same group show similar chemical properties and they also have the same number of valence electrons. The periodic table lists the elements in order of increasing atomic number. Most periodic tables provide additional data (such as atomic mass) in a box that contains each element’s symbol. For instance the Group 1 elements are referred to commonly as the 'alkaline metals'. A modern version is shown in Figure 2.4.1 2.4. Some groups within the periodic table are given special names. 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 periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. Period A horizontal row in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Group A vertical column in the periodic table. 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. The name is derived from the Latin calx meaning lime. Elements that exhibit similar chemistry appear in vertical columns called groups (. The periodic table is used as a predictive tool that arranges of the elements in order of increasing atomic number. There are total 18 vertical columns on periodic table. 4.6: The Periodic Table of the Elements is shared under a CC BY 4.0 license and was authored, remixed, and/or curated by LibreTexts. The columns of this table are called groups. \right)\).Groups are the vertical columns on the periodic table. Modern chemists have assigned each of the 118 chemical elements known currently to a slot in the periodic table.
