All the Group 1 elements are very reactive. They have a strong tendency to donate their valence electron in the last shell to form strong ionic bonds. Describes the structures and physical properties of the elements, and some important atomic properties. Group 4 chlorides . . Looks at the increasing tendency towards an oxidation state of +2 as you go down the Group. The group 13 elements consist of six elements. You already know they can be called group 4A, but they can also be referred to as group 14 or group IVA. Questions of this type are frequently asked in competitive entrance exams like CBSE Class 10 and are Group 1: The Alkali Metals The Elements Properties are dominated by the fact that they lose their e-easily Most Violently reactive of all the metals React strongly with H 2 O(l) the vigor of the reaction increase down the group (ex: 2Na(s) + 2H 2 O(l) Æ2NaOH(aq) + H 2 (g)) The alkali metals are all too easily oxidized to be found in their
They have the least nuclear charge in their respective periods. .

As we move down the group, the atomic radius increases. Also Known As: Elements belonging to this group are also known as pnictogens, at term derived from the Greek word pnigein, which means "to choke".This refers to the choking property of nitrogen gas (as opposed to air, which contains oxygen as well as nitrogen). The Group 1 elements are called the alkali metals. . Group 3 is a group of elements in the periodic table.This group, like other d-block groups, should contain four elements, but it is not agreed what elements belong in the group. This element gets the name of ununtrium [Uut]. Answer with step by step detailed solutions to question from HashLearn's X CBSE: Chemistry, Periodic classification of Elements- "The group 14 elements are called " plus 160 more questions from Chemistry. Oxidation state trends . They are placed in the vertical column on the left-hand side of the periodic table.
. Therefore, the nuclear charge decreases. The general electronic configuration of Group 1 elements is ns 1. The commonest property of the group is that each one of the elements has three electrons in the outer shell of their nuclear structure. They are boron (B), aluminium (Al), gallium (Ga), Indium (In), thallium (Tl), and element 113. All mean the same thing. Discusses the trend from non-metallic to metallic behaviour as you go down Group 4. Properties of Group 4A Elements All mean the same thing.
