Because they have seven valence electrons and therefor only need one to react and have eight valence electrons.
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
Magnesium is most reactive with Group 17 elements, also known as the halogens. The reaction of magnesium with halogens, such as chlorine or fluorine, typically results in the formation of ionic compounds, with magnesium donating electrons to the halogen atoms.
The Halogens are most reactive non-metals. They have the most tendency to accept electrons in their respective periods. The Halogen family comprises of Fluorine, Chlorine, Bromine, Iodine and Astatine
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.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Halogens among halogens fluorine is most reactive
The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the Periodic Table, and the halogens are the most reactive...
The most reactive family of nonmetals is the halogen family.
The most reactive nonmetal is fluorine
halogens are the most reactive nonmetal family
It is true that halogens are most reactive non-metals. This is because of two reasons:-They have only seven electron in their outermost shell. Thus, they get stable configuration only on gaining one electron.Also, halogens are the most electronegative elements and have very attracting power for electrons.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)
Francium is the most reactive metal and fluorine the most reactive nonmetal.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
Group 17 or 7-A, the halogens, are the most reactive non-metals.
fluorine is the most reactive
