Noble gases (or group 18 elements)
The grup 8 elemnts are quite unreactive- the term noble was I think coined for gold and other unreactive metals- and the adjective got re-used- they were once called the inert gases- but this is no longer true as unstable reactive compounds have been made for Argon and the heavier members of the group.
The elements in group 17 are known by the name halogens. They are non-metal elements and are at times referred to as salts.
Group 1 Metals
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group 16 of the periodic table of the elements (chalcogens elements)
The group of unreactive nonmetals that includes argon is called the noble gases. These elements are characterized by their full outer electron shells, making them stable and unreactive under normal conditions.
Noble gases, such as helium, neon, and argon, will never react with other elements. They have a full outer electron shell, making them stable and unreactive.
Group 18 on the Periodic Table contains the Inert Gases. Inert Gases tend to be unreactive. This group has the elements Helium, Neon, Argon, Krypton, Xenon, and Radon.
Group 8A, also known as group 18, are very non-reactive. However, they are all gases, not transition metals. Transition metals are the large family of elements in the middle of the table in between groups 2 and 13 (2A and 3A). Group 8A are the noble gases.
These elements are francium and lithium.
I'm pretty sure that groups 3-12 (which includes 7) on the Periodic Table are classified as Metalloids.
The family of elements in Group VIIIA 18 is known as the noble gases. They are characterized by their stability due to having a full outer electron shell, making them generally unreactive. The noble gases include helium, neon, argon, krypton, xenon, and radon.
Another name for Group 17 (VIIA) Elements is Halogens.
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). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds
