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.
Alkaline metals are reactive because they have one electron in their outermost shell, which they readily lose to achieve a stable electronic configuration. Halogens are reactive because they have seven electrons in their outermost shell and therefore tend to gain one electron to achieve a stable electronic configuration. This tendency to gain or lose electrons makes both alkaline and halogens highly reactive.

What element is a reactive metal that attacks water?
Sodium is a reactive metal that attacks water, producing hydrogen gas and an alkaline solution of sodium hydroxide.
What are two most reactive groups in the periodic table?
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
What term describes the most reactive nonmetals that have seven valence electron?
Halogens.
Who has the most active group of nonmetals noble gases alkaline earth halogens alkali metals?
The halogens have the most active group of nonmetals. They are highly reactive due to their incomplete outer electron shells, which makes them eager to gain an electron to achieve stability. This reactivity is why halogens are often found bonded to other elements in nature.
Which property is common to all halogens?
All halogens have seven valence electrons in their outermost energy level, making them highly reactive nonmetals.
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)
Halogens are radioactive or not?
No, halogens are reactive however and can be dangerous.
The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
The most reactive group of the nonmetals are the?
Halogens among halogens fluorine is most reactive
What element is a reactive metal that attacks water?
Sodium is a reactive metal that attacks water, producing hydrogen gas and an alkaline solution of sodium hydroxide.
Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
