If you're referring to the Periodic Table, the group one and two elements (Alkali and Alkaline earth metals) react with water very vigorously, often explosively in the Alkali metals. The transition metals react VERY slowly, as water can be considered an oxidising agent, to form the respective oxides. This can be seen in Iron(III) oxide, as the red rust is formed when iron metal is left in contact with moisture.
The alkali metals, found in Group 1 of the periodic table, are the most reactive chemical family. They readily lose their outer electron to form cations, leading to highly exothermic reactions with water and oxygen.
The boron family is moderately reactive. Boron itself is a relatively unreactive element, while the elements below it in the group, such as aluminum, can be more reactive due to their ability to form stable compounds with other elements.
The most reactive non-metals are the halogens, group 17.
Potassium is highly reactive, even explosive in some circumstances.
Lead is a moderately reactive metal. It reacts slowly with air and water, but does not react as vigorously as highly reactive metals like sodium or potassium.

Reactive power is the coarse that is reactive with water. This a developing composite material.
less reactive
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
The alkali metals, found in Group 1 of the periodic table, are the most reactive chemical family. They readily lose their outer electron to form cations, leading to highly exothermic reactions with water and oxygen.
The most reactive nonmetal is fluorine
The noble gases are the least reactive among all chemical elements.
halogens.
noble gases
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
Yes, halogen family is considered highly reactive. It easily gains 1 electron to form anion.
The reactive force would be gliding through the water.
