What are the most reactive metals called?

The group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with air and water. The reactivity of the alkali metals increases down the group. Flame tests are used to identify alkali metal ions in compounds.

In this regard, which is the most reactive element?

Caesium and fluorine. Group I metals are the most reactive metals as they only have one electron in their outer shell which is easy to lose; they get more reactive as you go down the periodic table as the electron is further from the nucleus and shielded by the inner electrons.

What is the most reactive group of metals?

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.

What are the most reactive metals on the periodic table?

The alkali metals, found in group 1 of the periodic table, are highly 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.
