Which group of metals are the MOST reactive?
The alkali metals, which include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr), are generally considered to be the most reactive group of metals. They are highly reactive due to their low ionization energies and tendency to lose one electron to achieve a stable electron configuration.
The most reactive group of metals is Group 1, also known as the alkali metals. Alkali metals include elements such as lithium (Li), sodium (Na), potassium (K), and so on. They are located in the first column of the periodic table.
To determine which group of metals is the most reactive, you can refer to the periodic table. The reactivity of metals generally tends to increase as you move down a group. This is because the outermost electron in alkali metals is loosely held due to their low ionization energy. As a result, alkali metals readily lose their valence electron to form positive ions and react vigorously with other substances, including water and air.
It is important to note that Group 1 metals are highly reactive and can be dangerous if not handled properly. They must be stored in mineral oil or other inert materials to prevent oxidation and reaction with moisture in the air.
