Question

Where are the most reactive metals on the periodic table?

Answer 1

on the periodic table, alkali metals are the most reactive ones and are found in the first group of elements on the left side of the table. Alkali metals such as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr) are reactive because they have extra electron which they are trying really hard to get rid of. Once they get rid of this electron, these elements have a full octet.

Answer 2

Among the metals, group 1 elements are the most reactive because they have only one valence electron. They tend to lose this electron to attain a stable configuration. As we move down group 1, the elements lose their electrons more readily. So, rubidium is the most reactive metal. Among the nonmetals, group 7 elements require only one electron to attain a stable electron configuration. The affinity for electrons decreases in the group from top to bottom. So, fluorine is the most reactive nonmetal.
