Reference:ġ.“Definition of Representative Element.” Sciencing, Available hereĢ.“Transition metal.” Wikipedia, Wikimedia Foundation, 25 Feb. The difference between representative elements and transition elements is that, representative elements are the chemical elements in the group 1, group 2 and in the groups from 13 to 18 whereas transition elements are chemical elements in group 3 to group 12 including Lanthanides and Actinides. Transition metals are in the d block and the f block of the periodic table. ![]() Representative elements are the main group elements that include alkali metals, alkaline earth metals, nonmetals and noble gases. Summary – Representative vs Transition Elements Most of the compounds formed by representative elements are colourless.Īll the compounds formed by transition elements are colourful. Transition elements are in the groups 3 to 12. Representative elements are in the group1, group 2, and in groups 13 to 18. Transition elements include d block and f block elements. Representative elements include s block and p block elements. Transition elements are chemical elements that have unpaired d electrons at least in a stable cation that is can form. Representative elements are the chemical elements in the group 1, group 2 and in the groups from 13 to 18. When these electrons come back to the previous orbital, it emits the absorbed energy as visible light). The reason for this color is the presence of unpaired d electrons (it allows the electrons to jump from one orbital to another by absorbing energy. And also, the captions containing the same transition elements with different oxidation states can have different colors based on the oxidation state (the color of the cation varies with the oxidation state of the same chemical element). Zn +2 is the only stable cation of zinc).Īlmost all the transition metals have multiple stable oxidation states in different compounds. Therefore, all the chemical elements from group 3 to group 12 are transition metals excluding zinc (because zinc has no unpaired electrons and Zn +2 also has no unpaired electrons. They have their valence electrons in the outermost d orbitals. Alkaline earth metals include Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium. Alkali metals include Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. These metals are named as such because they form basic or alkaline compounds. Alkali metals are group 1 elements (excluding hydrogen) whereas alkali earth metals are group 2 elements. S block elements have their valence electrons in the outermost s orbitals and are in two types as alkali metals and alkaline earth metals along with hydrogen and helium. S block elements (Alkali metals and alkaline earth metals).Representative elements are also known as “group A elements” or “s block and p block elements” or “main group elements”, meaning representative elements include the following groups of chemical elements Summary What are Representative Elements? Side by Side Comparison – Representative vs Transition Elements in Tabular Formĥ. ![]() The key difference between representative elements and transition elements is that representative elements are the chemical elements in the group 1, group 2 and in the groups from 13 to 18 whereas transition elements are chemical elements in group 3 to group 12 including Lanthanides and Actinides. ![]() All the elements in the periodic table can be divided into two groups as representative elements and transition elements. There are periodic trends in the periodic table. There are rows or periods and columns or groups in the periodic table. The periodic table of elements is a tabular arrangement of all known chemical elements based on their atomic numbers. Key Difference – Representative vs Transition Elements
