They are extremely reactive. When combined with water they oxidize and release hydrogen gas and lots of heat. Their outer shell of electrons is very weakly held on and so they can easily ionize to 1+ state.
The chemical reactivity of alkali metals increase when the atomic number increase.
The most attractive property of alkali metals is their high reactivity, which is primarily due to their single valence electron. This electron is easily lost, allowing alkali metals to readily form positive ions and engage in chemical reactions, particularly with nonmetals like halogens. Their low ionization energies and low electronegativities further enhance their reactivity, making them highly effective in forming compounds. Additionally, this reactivity increases down the group, making heavier alkali metals even more attractive in terms of their chemical behavior.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Halogens.
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
Very reactive elements are alkali metals and halogens.
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
Three families from the periodic table are the alkali metals (group 1), the halogens (group 17), and the noble gases (group 18). Alkali metals are highly reactive, halogens are nonmetals that are also reactive, and noble gases are inert gases with low reactivity.
Chlorine belongs to the reactivity group of halogens. Halogens are highly reactive nonmetals that readily form compounds with other elements. Chlorine, in particular, is known for its strong oxidizing properties.

The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.
An ionic bond is formed by electron transfer between alkali metals and halogens.
The most active metals are alkali metals.The most active nonmetals are halogens.
