They only need 1 electron to gain a full outer shell as the Halogens are Group VII. They are very similar to the Group I metals, which, in retrospect, need to lose/give away 1 electron to achieve the same goal. This is typically why they are so reactive.

Do the halogens become more reactive or less reactive as they go lower down the group?
The most reactive halogens - fluorone and chlorine - are in the upper part of the group.
Why are the alkali metals and halogen among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Is the non metal lodine strongly reactive?
Yes because it is part of the halogens and in general halogens are the most reactive non metals
Are halogens more reactive than actinides?
No actinides are more reactive
What is a characteristic property of halogens?
They are very reactive.
Are halogens reactive?
Yes, halogens are extremely reactive.
Which is the most reactive of the halogens and why is it the most reactive of the halogens?
fluorine is the most reactive
Why are the alkali metals and Halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Why alkali metals and the halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Most reactive group of nonmetals?
The Halogens. Fluorine, Chlorine, Bromine, Iodine and Astatine, with Fluorine being the most reactive.
The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
Does halogens have high or low reactivity?
Halogens have highreactivity.
Halogens are radioactive or not?
No, halogens are reactive however and can be dangerous.
The most reactive group of the nonmetals are the?
Halogens among halogens fluorine is most reactive
Do the halogens become more reactive or less reactive as they go lower down the group?
The most reactive halogens - fluorone and chlorine - are in the upper part of the group.

Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
