Because they have seven valence electrons and therefor only need one to react and have eight valence electrons.

∙ 12y agoWith 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.

With which group of elements is magnesium most reactive?
with group 17 elements or halogens
Which group are highly reactive non metals on the periodic table?
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.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Which of the two halogens shown is more reactive?
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.
Most reactive non metal?
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.
The most reactive group of the nonmetals are the?
Halogens among halogens fluorine is most reactive
What group of non metals are the 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...
Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
Which elements of the halogen family is the most reactive nonmetal?
The most reactive nonmetal is fluorine
What is a halogen and is found in what group?
halogens are the most reactive nonmetal family
Where on the periodic table is most reactive nonmetal?
The most reactive nonmetals are the halogens in group 17 of the periodic table.
Are Halogens the most reactive nonmetal?
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.
What gas is the most reactive of all elements?
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 what?
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
With which group of elements is magnesium most reactive?
with group 17 elements or halogens
What groups of nonmetal is most reactant?
Group 17 or 7-A, the halogens, are the most reactive non-metals.
Which is the most reactive of the halogens and why is it the most reactive of the halogens?
fluorine is the most reactive
