Group III-B or 4th, it includes 4 elements of 'd' block and all the 28 elements of 'f' block.
Group 3 of the periodic table contains many of the radioactive elements.
Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.
group 17 or halogens
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
the vertical column is called group in the periodic table.
Group 1, the far left most group.
Generally group 1 elements.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
The most electronegative elements are found in the top right corner of the periodic table, in the halogen group (Group 17). These elements include fluorine, chlorine, bromine, iodine, and astatine.
The United States has the most elements on the periodic table.
