well basically they all have very unstable atoms and having unstable atoms.
They also have only 1 outer electron and only then is an atom happy when it has a full outer shell.. This means that the alkali metals want to get rid of their extra electron and therefore means they would be very reactive with the group 7 metals.
Hope this helps :D

What property of metals are reactivity?
It means metals that are highly reactive. It's one of the most self-evident pieces of terminology in all of chemistry. Perhaps you were trying to ask which metals are considered "highly reactive", which is a separate question, and one that to some extent depends on your definitions, but would certainly at minimum include all the alkali metals, maybe the alkaline earth metals, and possibly a few selected others (aluminium, for example... we don't usually think of aluminium as "highly reactive" because it immediately forms a thin transparent protective layer of aluminium oxide when exposed to air, but without that layer, it is indeed pretty reactive).
Which group of metals is highly reactive?
Group 1 on the periodic table, known as the alkali metals, are the most reactive group of metals. They all share the chemical property of having just 1 valence electron. First ionization energies for these elements is quite low, and as you go down the group from top to bottom it gets lower. The alkali metals are so reactive that they do not exist elementally in nature; only in compounds. Sodium and potassium are the most common. Francium is the rarest.
What characteristics are shared by all alkali metals?
All alkali metals have one valence electron, making them highly reactive. They are soft, shiny, and have low melting points. They are typically found in nature in compounds rather than in their pure metal form.
Why are alkali metals rarely found as pure elements?
They are highly reactivated. they are reacting with other compounds.
Is chlorine the most or least reactive of all elements?
Neither. Chlorine is among the most highly reactive nonmetal elements, but fluorine and oxygen are even more reactive, as are the heavier alkali and alkaline earth metals.
What characteristics are shared by all metals and alkaline earth metals?
They are highly- reactive metals
How many reactive metals are there?
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
Are alkali earth metals liquids?
no, the alkali metals make up the first period and all of them are highly reactive.
What is a very reactive non metals?
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
Which set of elements make up the reactive group of all metals?
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.

Highly reactive metals?
All the ALKALI METALS are highly reactive. The alkali metals are a series of chemical elements forming Group 1 (IUPAC style) of the periodic table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
What are some properties of group 17 on the periodic table?
Group 17 (the halogens) are all highly reactive non-metals.
Which group of metals is highly reactive?

What are features of the alkali metals?
Alkali metals have only one valence electron and all of these elements are highly reactive. All of them are metals. Except lithium, other elements can be cut by a blade. They have a lesser density than water.
