The name of the group is the oxygen family. The valence number for elements in that group are -2. (gain or share two electrons) Oxygen, sulfur and selenium are nonmetals. Tellurium and Polonium are metalloids.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
Oxygen is the most active nonmetallic element in group 16, also known as the oxygen group or chalcogens. It readily reacts with many elements to form oxides.
No, chlorine is not a metalloid. It is a halogen, a group of nonmetallic elements known for their high reactivity. Metalloids are elements that have properties of both metals and nonmetals.
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
The periodic table generally contains more metallic elements than nonmetallic elements. Metals are found on the left side of the periodic table and make up the majority of elements, while nonmetals are mostly located on the right side. However, there are exceptions, such as the metalloids group that have properties of both metals and nonmetals.

Group 18
what property does each of the elements have
Its group 16
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
The periodic table generally contains more metallic elements than nonmetallic elements. Metals are found on the left side of the periodic table and make up the majority of elements, while nonmetals are mostly located on the right side. However, there are exceptions, such as the metalloids group that have properties of both metals and nonmetals.
No, phosphorus is not a halogen. Phosphorus is a nonmetallic element in group 15 of the periodic table, while halogens are a group of elements in group 17 of the periodic table that include fluorine, chlorine, bromine, iodine, and astatine.
