Alkali metals
The elements in group one are the alkali metals.
Alkali metals. This is the most reactive group on the periodic table
Group I of the periodic table is called the Alkali Metals group (Hydrogen-Lithium group)
group one
The column of the periodic table is called group. It is also referred as family.

alkali metals
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
Group 1 on the periodic table consists of alkali metals. These elements are highly reactive and have one electron in their outer shell. The group includes elements like sodium, lithium, and potassium.
The halogens group is a group of nonmetal elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. These elements are highly reactive and can form salts by gaining one electron to achieve a full outer shell. They are located in Group 17 of the periodic table.
Bromine
Helium is the element that is placed in period 1 and group 18 of the periodic table. It is inert in nature and hence stable.
