Halogens, such as chlorine, iodine or fluorine.
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
Alkali metals exist only as salts.
Group 1 Alkali metals because the halogens need one electron to fill their outer electron shell.
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.
Li, Na, K, NH4
These salts are weak electrolytes: examples are acetates, formates etc. of alkali metals.
Magnesium oxide is a basic compound, also known as an alkali. It reacts with acids to form salts and water.
Those salts which can dissolve in water.because water is a solvent and salts are solute.
The products of the reactions are ionic salts.
Rule 2
Alkali metals, halogens, and noble gases are distinct groups in the periodic table, each with unique properties. Alkali metals (Group 1) are highly reactive, especially with water, and have one valence electron. Halogens (Group 17) are also reactive, with seven valence electrons, and readily form salts with alkali metals. In contrast, noble gases (Group 18) are largely inert due to having full valence electron shells, making them stable and unreactive under normal conditions.
Many metals reacts with acids forming salts.
