What are main group elements examples?
Specific examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
What are the main groups of elements called?
The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties. There are some elements that show some, but not all, of the metallic properties.

How many main group elements are there?
18
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Where are the main group elements?
The main group elements are those in the s and p blocks of the periodic table, as shown in Figure 8.2. 1. Figure 8.2.
Is Na a main group element?
Abstract. The main group elements are classified as belonging to the s- and p-blocks in the periodic table. They range from gases such as fluorine and oxygen through nonmetals (e.g., boron, phosphorus, and sulfur) and semimetals (metalloids; e.g., germanium) to very reactive metals such as sodium and potassium.
Is yttrium a main group element?
Other Main Group Elements A few scientists include the group 3 elements (scandium and yttrium) and sometimes the lanthanides and actinides.
What are group 8 elements called?
noble gases
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
