In group 1 of the periodic table, all the elements except hydrogen (H) are alkali metals. Elements in the periodic table are arranged according to their atomic number. Group 2 is the alkali earth metals which have two valence electrons, filling their s sublevel. Further Explanation Periodic table Periodic table is a table that contains elements arranged in columns called groups and rows called periods. Copyright © 2021 Multiply Media, LLC. Best answer. The elements in Group 2A are called the _____. 5. 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. However, IUPAC recommends that the numbers 1 through 18 be used, and these labels are more common. answered Aug 23, 2019 by Skank01 . Groups 3-12 are termed d-block elements. On the other hand, any nontrivial finite group cannot be free, since the elements of a free generating set of a free group have infinite order. Have you ever wondered why are group 2 elements called alkaline earth metals? From calcium downward, the alkaline earth metals react with room-temperature water, but the reaction is slower and not as violent as a reacti… elements in group VIIIA are called the noble gases orthe inert gases. Oxygen is a gas at room temperature. New questions in Science. Compare this with the coloured compounds of most transition metals. The noble gases are in Group 18 (8A).They are helium, neon, argon, krypton, xenon, and radon.They were once called inert gases because they were thought to be completely inert—unable to form compounds.This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements in group two are called the alkaline earth metals. Four of the six group 2 elements—magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba)—were first isolated in the early 19th century by Sir Humphry Davy, using a technique similar to the one he used to obtain the first alkali metals. The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row elements are actinides; Figure 3). Further Explanation Periodic table Periodic table is a table that contains elements arranged in columns called groups and rows called periods. Noble Gases. So in Group 15 elements as you would move down a group, starting with the lightest element and finishing with the heavy ones; you’d notice a general flow in properties as you move down the order. https://www.answers.com/Q/What_are_the_elements_in_Group_2_called You will get the exact answer here (with examples) Here is your answer: When alkaline earth metals (i.e Be, Mg, Ca, Sr, Ba and Ra) react with water, they form hydroxides which are alkaline in nature (or basis in nature). (3) Both group 1 and group 2 elements produce white ionic compounds. 6. The general electronic configuration of Group 2 elements is ns 2. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. Alkali Earth Metals – Group 2 Elements Included in the group two elements are Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), and Barium (Ba). 0. Hydrogen is a nonmetal grouped with the alkali metals because it has one electron in its valence shell. Periodic Trends in Group 15 Elements. Occurrence of group 16 elements of the modern periodic table. Main group elements in the first two rows of the table are called typical elements. • Define allotropes and provide examples. Group 18 elements, on the far right side of the table, for example, have completely full outer shells and rarely participate in chemical reactions. Seven valence electrons, so elements from this group typically exhibit a -1 oxidation state; Noble Gases . The most active element in Group 17 is. They include lithium, sodium, potassium, strontium, etc. Transition Metals. All Rights Reserved. FALSE. Usually, there is no need to store these elements in oil, unlike the group one elements. Unlike other groups, noble gasses are unreactive and have very low electronegativity or electron affinity. How old was Ralph macchio in the first Karate Kid? alkaline earth metals 0 votes. Noble Gases []. The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals. asked Aug 23, 2019 in Chemistry by Amaly.

For a metal, alkali earth metals tend to have low melting points and low densities. Later, he suggested that the alkaline earths might be metal oxides, but admitted that this was mere conjecture. Elements in group 2 are all called alkaline earth metals. When the 3 electrons are lost, a full shell of 8 electrons is exposed, creating more stable conditions. Beryllium, for example, is unable to react with water at all, while magnesium reacts with steam, but not water in the liquid phase. Where is Jesse De-Wilde son of Brandon deWilde? There are 18 groups in the standard periodic table. Although an element group often is defined as a column of the periodic table, it's common to refer to groups of elements that span multiple columns, excluding some elements. Period 2 and Period 3 both have 8 elements. This can be explained using the inert pair effect. Because they have 2 valence electrons they are less reactive than group 1. 1. Noble gases. Elements in Group 2 are classified as alkali metals. • Explain the importance to organisms of selected p-block elements. The noble gasses have complete valence electron shells, so they act differently. Alkali earth metals have the capability to lose the two electrons in their outer shell. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. This is called covalent bonding. Group 3 elements can react by losing 3 electrons. 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. They are the electrons involved in chemical bonds with other elements. Group 15 elements are sometimes called the pnictogens. Elements in group 2 are all called alkaline earth metals. Group 16 is called the oxygen group. They are followed by one metalloid and one metal. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.

The alkaline earths are the elements located in Group IIA of the periodic table. The cause of there inertness is: Electronic Configuration Every Noble Gas has completed its octet, means it has 8 electrons in its valence shell. These metals have just two valence electrons, so they are very reactive, although not quite as reactive as the alkali metals. That's why it doesn't want to make ions or mutually share its electrons to make covalent bonds.
