Boron is the first element in Group 3A, and is the indecisive member of this family of 3A elements. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.There are 18 numbered groups in the periodic table; the f-block columns (between groups 3 and 4) are not numbered. Elements in Group 2 are classified as alkali metals. How long will the footprints on the moon last? Every element in the first column (group one) has one electron in its outer shell. Transition elements are those whose atoms have an incomplete d-subshell or whose cations have an incomplete d-subshell. In additive notation, the requirement for an element to be primitive is that each element of the group can be written as Elements in a group have the same number of electrons in their outer shell, and also the same charge 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. Such an element a is called a generator or a primitive element of the group. The columns The Group 2 elements are: 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 ns2. FALSE. Halogens. Members of the boron group include: Noble Gases. Other periods are longer. Group 2: Alkaline Earth Metals The alkaline Earth metals include all the elements in group 2 (see Figure below). They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The vertical columns on the periodic table are called. However, IUPAC recommends that the numbers 1 through 18 be used, and these labels are more common. Groups 1-2 termed s-block elements. Group 2 elements generally react to form compounds in which the group 2 element has an oxidation state of +2, beryllium will also do this but it has a tendency to form covalent rather than ionic compounds. 1.
