∙ 12y agoHelium is the least active nonmetal in the Periodic Table. It is a noble gas with a full outer electron shell, making it very stable and unreactive under normal conditions.
The first nonmetal on the fourth row of the periodic table is oxygen.
Helium is the least reactive nonmetal on the periodic table. It is a noble gas with a full outer electron shell, which makes it very stable and unreactive with other elements.

No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
The element Neon
The most active metals are typically located in Group 1 (alkali metals) of the periodic table. The most active nonmetals are usually found in Group 17 (halogens) of the periodic table.
Fluorine is the most active nonmetal in the periodic table due to its high electronegativity, making it highly reactive and capable of forming strong bonds with other elements.
Bromine is a nonmetal element that is in the correct group on the periodic table.
Water isn't on the periodic table as it is a compound and only elements are on the periodic table

Bromine.
metalloids
The most reactive nonmetals are located in the top right corner of the periodic table within Group 17, also known as the halogens. Elements like fluorine, chlorine, bromine, and iodine are highly reactive nonmetals due to their strong desire to gain an extra electron to achieve a stable electron configuration.
