Join now. The alkaline part of the name comes from the fact that these metal form alkaline solutions, when they react with water. They are called alkaline earth metals because they form alkaline solutions (hydroxides) when they react with water . The alkaline earth metals are a group of elements in the periodic table. Alkali metals are in Group 1 of the periodic table and all have 1 valence electron that they readily lose to become more stable. Group 2 elements are called alkaline metals because they form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust. The alkaline earth metals comprise the group 2 elements. Reactions of Alkaline Earth Metals. The alkaline earth metals as their oxides and hydroxides are alkaline, 1 of 32. What is most similar about the alkaline earth metals? For a metal, alkali earth metals tend to have low melting points and low densities. • They are similar in many ways to group one but are less reactive. When Group 2 metal are burned in oxygen, you get a solid white oxide. Originally Answered: Why are group 2 elements called alkaline earth metals? The earth part was added to differentiate these from the group one metals. The alkaline earth metals are very reactive, although less so than the alkali metals. What is Group 2 called? You'll find more specific groups, like transition metals, rare earths, alkali metals, alkaline earth, halogens, and noble gasses. All the discovered alkaline earth metals occur in nature. Heading to Group Two So we just covered the alkali metals in Group I. The Melting And Boiling Points Are Much For 2A Metals Than For The Corresponding 1A Metals. Group 1 elements are indeed called alkali metals because of what happens when they react with water. 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. Group 2 Elements are called as alkaline earth meats because they are less reactive than that of group 1 metals. From calcium downwards, the melting point decreases as delocalised electrons are further away from the nucleus. • Beryllium is not typical of the group, however, and is thus not considered here. 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. 2 The alkaline earth elements are metallic elements found in the second group of the periodic table. PLAY. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The second row of the f -block elements are called actanoids (or, less desirably, actanides. So basically, this term alkaline means that the solution has a pH greater than seven and is basic.

Group 7A elements are called halogens. Reactions of Alkaline Earth Metals. All the discovered alkaline earth metals occur in nature. They are sometimes referred to as the group 2 elements. Find an answer to your question Why are group 2 elements called alkaline earth metals? The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are all in the second column of the periodic table. Ask your question. 1. Because they produce alkaline aqueous solutions.
