The elements are stacked in such a way that elements with similar chemical properties form vertical columns, called groups, numbered from 1 to 18 (older periodic tables use a system based on roman numerals). they are called so because they are harder and less reactive than 1st group. The actinides and the lanthanides together form a group called the inner transition metals. How can the periodic table be used to predict the properties of the elements? 1. Like the group 14 elements, the lightest member of group 15, nitrogen, is found in nature as the free element, and the heaviest elements have been known for centuries because they are easily isolated from their ores.Antimony (Sb) was probably the first of the pnicogens to be obtained in elemental form and recognized as an element. The following names for specific groups in the periodic table are in common use: In addition, groups may be idenitifed by the first element in each group - so the Group 16 set of elements is sometimes called the oxygen group. The non-metals in this family react by gaining 4 extra electrons through the formation of covalent bonds (sharing bonds). That term does not encompass scandium and yttrium. The Group 7 elements are called the halogens. Main group elements in the first two rows of the table are called typical elements. 1.

They all are also called pnicogens, a famous term used many times because they form very explosive substances for example TNT is nothing but trinitrotoluene which is highly explosive and contains nitrogen. All other groups on the table (1, 2, 13-18) are called Main Group Elements. The second row of the f -block elements are called actanoids (or, less desirably, actanides. The other two systems are less desirable since they are confusing, but still in common usage. Halogens. The p-block elements are also known as the Representative Elements which is placed on the right side of the main periodic table.. In the periodic table Group III formerly covered what are now called: Phosphorus on exposure to air burns vigorously and its compounds also … The noble gasses have complete valence electron shells, so they act differently.

Groups 1-2 (except hydrogen) and 13-18 are termed main group elements. Groups 1-2 termed s-block elements. They are called. These groups contain metals that usually form multiple cations. Boron is the only element in this group that is not a metal. The most active element in Group 17 is. They are sometimes also called the representative elements and they are the most abundant in the universe. In each of the four periods in which they occur, these elements represent the successive addition of electrons to the d atomic orbitals of the atoms. The two variants originate from historical difficulties in placing the lanthanides in the periodic table, and arguments as to where the f block elements start and end. Seven valence electrons, so elements from this group typically exhibit a -1 oxidation state; Noble Gases . These elements exhibit the characteristic properties of metals and are often found in more than one oxidation state. Groups 3-11 are termed transition elements. Elements of Group 3-12 are called.
