Alkaline and halogens are reactive because usually they are attracted to each other. Why? Because halogens have seven valence electrons, or electrons in their outermost shell, while alkaline metals only have one valence electron. An example of a halogen is florine and chlorine. An alkaline metal example is hydrogen and lithium.

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.
What are the reactive groups of fatty acids?
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
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 the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
What groups is the most reactive alkaline earth or alkali or halogens or noble gases?
I think alkali is the most reactive one.
Properties of alkaline earth metals?
They are extremely reactive with acid -explosively in some cases. They are also very reactive with water and form alkaline solutions and also very reactive with halogens. Apart from that they have the usual properties of metals such as ductility and lustre etc.
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.
What do halogens all have in common?
Well one answer is pretty obvious, they're all called halogens. And here are ones I got from chemistry.about.com "Very high electronegativities Seven valence electrons (one short of a stable octet) Highly reactive, especially with alkali metals and alkaline earths "
