Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table. BII. The alkaline earth metals are the elements that correspond to group 2 of the modern periodic table. As one goes down the group, the atoms have more shells of electrons making the atom bigger and there is a decrease in effective nuclear charge with successive elements because of increased screening, and so the electrons are less firmly held to the nucleus. 8 mins. Group 2 elements. Reactions of Alkaline Earth Metals. Alkaline Earth Metals? The basic metals are similar to transition metals but tend to be softer and to hint at nonmetallic properties. Sr - Strontium Ba - Barium Ra - Radium (Radioactive) These metals are known as alkaline earth metals as their oxides are alkaline and occur in earth crust. Alkali metals (Group 1) elements are soft, very reactive metals; Alkaline Earth metals (Group 2) are somewhat reactive metals that react easily with oxygen; Halogens (Group 17) are very reactive non-metals; Noble Gases (Group 18) are non-reactive, non-metals that are gases. Included in the group two elements are Beryllium(Be), Magnesium(Mg), Calcium(Ca), Strontium(Sr), and Barium(Ba). Barium forms barium peroxide (BaO 2) because the larger O 2 2− ion is better able to separate the large Ba 2+ ions in the crystal lattice. The chemical reactions of only magnesium and calcium are studied at GCSE. The alkaline earth metals are very reactive, although less so than the alkali metals. Group 2 The Alkaline Earth Metals. Answer Save. Alkaline earth metals make up the second group of the periodic table. Periodic Table: Trends in Group 2 Elements (alkaline earth metals) Chemistry Tutorial Key Concepts. The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr).These metals are called alkali metals because they form alkalies( i.e. Another point mentioned in the book by Bahadur, under the chapter "s-Block Elements - The Alkali Metals", under Complex Ion Formation is that the Group 1 metals, i.e., the alkali earth metals have a larger size, low nuclear charge and hence don't tend to form complexes too easily. Group 2 contains soft, silver metals that are less metallic in character than the Group 1 elements. ALKALINE METALS. Beryllium : Beryllium is a chemical element with the symbol Be and atomic number 4. The elements readily form divalent cations (such as Mg 2+ and Ca 2+). Like all members of a group, or family, the elements in Group 2 share certain common characteristics. VIEW MORE. It is used in the treatment of cancer.

Even though the name alkaline and alkali sound similar, I can assure you they are totally different. Alkali Earth Metals – Group 2 Elements. 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. 112 160 197 215 222 Atomic Radii nm 113 160 197 … They are located on the left side of the modern periodic table. The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) constitute group 2 of the periodic table. Like the elements in Group 1 (the alkali metals), the elements in Group 2 are chemically active and are never found in nature in the elemental state. The name alkaline metal comes from the fact that the oxides of the heavier members of the group react with water to form alkaline solutions. can you explain in some detail please? Why do sodium and potassium, which belong … Why are the two words "alkaline" and "earth" used to name the group 2 metals? All group 2 elements except barium react directly with oxygen to form the simple oxide MO. Group 2: The Alkaline Earth Metals Atomic radius Atomic radius increases down Group 2. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium … Electronegativity Trend. This is the second most reactive family of elements in the periodic table.Do you know why they are called alkaline?When these compounds are mixed in solutions, they are likely to form solutions with a pH greater than 7. 1 decade ago. Group 1 metals are less reactive than group 2 metals. The alkaline earth metals are all shiny, silver-white … Be - Beryllium Mg - Magnesium Ca - Calcium. Heading to Group Two So we just covered the alkali metals in Group I. Alkaline Earth Metals: Group 2 on the periodic table of elements, although they are less reactive than the alkali metals About Alkaline Earth Metals The alkaline earth metals are group 2 on the periodic table. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. The Group 2 Alkaline earth metals are the 2nd group in the periodic table and are just before the transition metals. True or False: Metalloids have properties of both metals and INNER TRANSITION METALS. If the Group 1 elements all have one electron in their outer orbital, we can predict that the Group 2 elements will have two electrons in that outer shell. As one goes down the group, the atoms have more shells of electrons making the atom bigger and there is a decrease in effective nuclear charge with successive elements because of increased screening, and so the electrons are less firmly held to the nucleus. GROUP 13 elements are the alkaline earth metals. Group 2 Elements: Alkaline Earth Metals. Learn Videos. Valence Electrons. … Class 11. Atomic Radius Trend. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). False, noble gases. This family includes the elements beryllium, magnesium, calcium, strontium, barium, and radium (Be, Mg, Ca, Sr, Ba, and Ra, respectively). Radium was discovered from the ore pitchblende by Madam Curie. 4 Answers. The lanthanides (rare earth) and actinides are also transition metals. Chemistry. 8 years ago.

Group 2 Elements are called as alkaline earth meats because they are less reactive than that of group 1 metals. Usually, there is no need to store these elements in oil, unlike the group one elements. The vertical columns in the periodic table of the elements are known as groups. Because of their high reactivity, the alkaline earths are not found free in nature. The alkaline earth elements. Each metal is naturally occurring and quite reactive. They are however not as reactive as the group 1 metals as they have 2 valence electrons instead of 1. For a metal, alkali earth metals tend to have low melting points and low densities. True or False: Group 18 elements are very unreactive elements known as TRANSITION METALS. 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. Group 2 elements almost exclusively form ionic compounds containing the M 2 + ion, they are more reactive toward group 15 elements, and they have a greater tendency to form complexes with Lewis bases than do the alkali metals. True. Lv 7. Beryllium is unusual and is not studied at GCSE. You will find the alkaline earth metals right next door in Group II. Alkaline Earth Metals . Answer Save. The elements in Group 2 of the periodic table are called the alkaline earth elements. Reactivity. Overview.
