Question

Which group in the periodic table is the most reactive

Answer 1

The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.

Answer 2

7thA group elements and 1stA group elements are mostly reactable except astatine and cesium as they are radio active elements
