Question: Elements in group 2 are all called alkaline earth metals. The Group 2 elements are: Beryllium; Magnesium; Calcium; Strontium; Barium; Radium; The electronic configuration of the elements consist of two s-electrons outside an inner core of electron corresponding to the previous inert gas: the group configuration is therefore ns 2. Reactions of Alkaline Earth Metals. The alkaline Earth metals Each group 2 element has two outer shell electrons, two more than the electronic configuration of a noble gas. what is most similar about the alkaline earth Contains elements in the solid, liquid, and gas phase a. alkali metals b. alkaline earth metals c. transition Ask your question. Chemistry; The Periodic Table; AS; AQA; Created by: Heather; Created on: 01-03-15 18:21; What are the elements in group 2 called and why? Group 2: The Alkaline Earth Metals Atomic radius Atomic radius increases down Group 2. • Beryllium is not typical of the group, however, and is thus not considered here. Their oxides and hydroxides are alkaline. ... the group 2 element is called a reducing agent because it has reduced another species. However, all of these elements do occur naturally. They are called alkaline earth metals because they form alkaline solutions (hydroxides) when they react with water . Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals.All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. STUDY. Alkali Earth Metals – Group 2 Elements. The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns 2). The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Included in the group two elements are Beryllium(Be), Magnesium(Mg), Calcium(Ca), Strontium(Sr), and Barium(Ba). The earth part was added to differentiate these from the group one metals. So basically, this term alkaline means that the solution has a pH greater than seven and is basic. From calcium downwards, the melting point decreases as delocalised electrons are further away from the nucleus. When Group 2 metal are burned in oxygen, you get a solid white oxide. Its valence shell contains 2 electrons; They have low electronegativity Group 2 Elements are called as alkaline earth meats because they are less reactive than that of group 1 metals. The following names for specific groups in the periodic table are in common use: Group 1: alkali metals. The alkaline earth metals are six chemical elements in group 2 of the periodic table. Group 2 contains soft, silver metals that are less metallic in character than the Group 1 elements. 1. Elements in group 2 are called alkaline earth metals, the most similarity about the alkaline metals is which chemical properties they have.. Further Explanation Periodic table Periodic table is a table that contains elements arranged in columns called groups and rows called periods. Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements. Hide Show resource information. Because of their high reactivity, the alkaline earths are not found free in nature. Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form. Reactivity increases down the group. • The elements in group 2 are sometimes called the alkaline earth metals, as their oxides and hydroxides are alkaline. The elements readily form divalent cations (such as Mg 2+ and Ca 2+). Originally Answered: Why are group 2 elements called alkaline earth metals? The alkaline earth elements are metallic elements found in the second group of the periodic table. Group 2 contains soft, silver metals that are less metallic in character than the Group 1 elements. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Introduction. Log in.
