Because they have seven valence electrons and therefor only need one to react and have eight valence electrons.
With greater ionization energy, nonmetals have greater reactiveness. This is because they don't want to lose electrons at all! They will instead gain electrons to complete the octet.This proves true in the element Fluorine.
Halogens are the most reactive group of nonmetals because they only need one electron to achieve an octet, which is a noble gas electron configuration, in order to become stable.
because they require only one electron to form stable configurations of the noble gases
having 1 electron in theis valance shell they can readly donate electron.
with group 17 elements or halogens
The more reactive elements on the periodic table are farther down in the rows. For example, Te, or Tellurium, is in group 16 and row 5. The elements in row 7 are the most reactive, but technically Tellurium, since it is the farthest down nonmetal on the periodic table, would be the most reactive nonmetal, technically making group 16 the most reactive row of the nonmetals.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.
The most reactive nonmetals are the Halogens, found in group 17. These elements tend to have 7 electrons in their outermost energy level (valence electrons). Since they only need one more electron to stabilize, they react easily to form a negative ion.
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
The most reactive nonmetals are the halogens in group 17 of the periodic table.
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.
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 halogens.
with group 17 elements or halogens
Group 17 or 7-A, the halogens, are the most reactive non-metals.
fluorine is the most reactive
