Oxygen (O), for example, readily reacts with metals to form compounds such as rust. Hydrogen is a nonmetal grouped with the alkali metals because it has one electron in its valence shell. Add your answer and earn points. The halogens and the alkali metals are very reactive groups. Noble Gases []. Group 3 elements can react by losing 3 electrons. Later, he suggested that the alkaline earths might be metal oxides, but admitted that this was mere conjecture. Asked By adminstaff @ 03/10/2019 03:22 PM. For a metal, alkali earth metals tend to have low melting points and low densities. When the 3 electrons are lost, a full shell of 8 electrons is exposed, creating more stable conditions. 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). Period 2 and Period 3 both have 8 elements. The Group 2 elements are called the alkaline earth metals. 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. TRUE . In contrast to the alkali metals, however, compounds of the alkaline earth metals had been recognized as unique for many centuries. 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. The modern periodic law says that "The properties of elements are periodic function of their atomic number." Each group has a number: from 1 to 18. Other periods are longer. Transition Metals. general-chemistry; 0 Answers. Groups 1-2 termed s-block elements. 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. The other four elements in group 16 are solids. Groups 13-18 termed p-block elements. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. Search for: Recent Posts. These metals have just two valence electrons, so they are very reactive, although not quite as reactive as the alkali metals. Thus, they react with other elements and form ionic compounds. 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. From calcium downward, the alkaline earth metals react with room-temperature water, but the reaction is slower and not as violent as a reacti… 3. Halogens. The elements in each group have the same number of electrons in the outer orbital. 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. As with the alkali metals, the properties depend on the ease with which electrons are lost. elements in group VIIIA are called the noble gases orthe inert gases. In the United States, the labels traditionally were Roman numerals with capital letters. The group number is an identifier used to describe the column of the standard periodic table in which the element appears. In group 1 of the periodic table, all the elements except hydrogen (H) are alkali metals. • Explain the importance to organisms of selected p-block elements. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. They are placed in the vertical column, second from the right, in the periodic table. Those outer electrons are also called valence electrons. Boron is the first element in Group 3A, and is the indecisive member of this family of 3A elements. Group 2: Alkaline Earth Metals The alkaline Earth metals include all the elements in group 2 (see Figure below). Periodic Trends in Group 15 Elements. And elements that have metal and nonmetal properties are metaloids. All the elements in Group 2 … Why are elements in groups 1A through 8A called representative elements? The alkaline earths are the elements located in Group IIA of the periodic table. In the Periodic Table, The elements of group 18 are all gases, but there are highly unreactive. 5.
