![]() Semi metals exhibit properties intermediate between those of metals and nonmetals. Contains two nonmetals, two metalloids, and one metal. The elements can be broadly divided into metals, nonmetals, and semi metals. There are two main groups on the periodic table: metals and nonmetals. Also, many periodic tables have a stair-step line on the table identifying the element groups. The metalloids separate the metals and nonmetals on a periodic table. ![]() Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. Updated on JanuElements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals. Elements that exhibit similar chemistry appear in vertical columns called groups (numbered 1–18 from left to right) the seven horizontal rows are called periods. The periodic table is an arrangement of the elements in order of increasing atomic number. Each group is located in a different part of the periodic table. On the left side of the zig-zag line, you will. Elements are either metals, nonmetals, or metalloids (or semi metals). As you can see from this color coded version of the Periodic Table, most of the elements are metals. Interestingly, the periodic table also separates the elements into metals, non-metals, and metalloids (figure 2).
