Alkali metals have only 1 electron in their outermost (ultimate) shell. This means the atom needs energy to loose only one electron to have a completely filled outermost shell.
Other atoms with 2 or 3 electrons would have needed more than twice or thrice the energy than these to loose electrons.
Hence alkali metals are highly reactive compared to others.
Like alkali metals, who need to LOOSE 1 electron to have a completely filled outermost shell, halogens need to GAIN 1 electron to have a completely filled outermost shell. With the same theory mentioned above, they are highly reactive.
What else can I help you with?
Are alkali metals considered to be very reactive or very unreactive?
Alkali metals are very reactive metals.
What reginon is very reactive metals found in the periodic table found in?
Very reactive metals are found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table.
Why property makes the alkali metals very reactive?
The alkali metals have a low electronegativity and they easily loss an electron.
Why is it unlikely to find pure alkali metals in a nature?
They are very reactive
What family of elements in the period table contains the most reactive metals?
The most reactive metals are the alkali metals in group 1a.

Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
What type of metal such as sodium have a single valence electrons and are very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
What type of metals such as sodium have a single valence electron and very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
What family is all metals are very reactive?
group 1, alkali metals

What metal is alkali metal?
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
What groups are the very reactive elements from?
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
Why is it unlikely to find pure alkali metals in a nature?
They are very reactive
What is the metallic properties?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
