Alkali metals and alkaline earth metals have 1 and 2 valence electrons respectively. If they lose these electrons, they will get the electronic configuration of the nearest noble gas (stable octet configuration) and hence they are very reactive.
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
Neither. Chlorine is among the most highly reactive nonmetal elements, but fluorine and oxygen are even more reactive, as are the heavier alkali and alkaline earth metals.
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Yes, the elements in Group 2 of the periodic table, known as the alkaline earth metals, are reactive, though less so than the alkali metals in Group 1. They readily react with water and acids, forming hydroxides and releasing hydrogen gas. Their reactivity increases down the group, with barium being the most reactive among them. However, they are generally less reactive compared to metals in other groups, such as the alkali metals.
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)

The alkali metals (Group 1) and the halogens (Group 17) are among the most reactive groups on the periodic table. Alkali metals readily react with water, while halogens are highly reactive nonmetals that easily form compounds with other elements.
The order of reactivity among classes of elements typically follows this pattern: alkali metals (most reactive), alkaline earth metals, transition metals, metalloids, nonmetals, and noble gases (least reactive). Alkali metals, such as lithium and sodium, readily lose electrons, making them highly reactive, especially with water. Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
Alkali earth metals are less reactive than alkali metals but they still react readily with oxygen and water, forming oxides and hydroxides. They are stored under oil or inert gases to prevent them from reacting with moisture in the air.
