The noble gases have a full outer electron shell, making them very stable and unreactive. This is because they already have a complete set of electrons, so they do not need to gain, lose, or share electrons with other elements to achieve stability.
Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
No, noble gases are not metals; they are a group of non-metal elements. Noble gases are the least reactive elements because they have a full valence shell of electrons, which makes them stable and unlikely to form chemical bonds with other elements. Alkali metals are the most reactive metals, while transition elements have varying reactivity levels depending on the element.
The halogens, periodic table column 17, are the most reactive nonmetals, because they have the highest electronegativities and therefore can strongly attract electrons from almost any other elements.

It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
The halogen group elements are reactive because they have seven valence electrons, making them one electron short of a full outer shell. They are highly reactive and tend to gain an electron through reactions with other elements to achieve a stable electron configuration.

The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.

Group 1 elements, known as alkali metals, include lithium, sodium, potassium, rubidium, cesium, and francium. They are characterized by having a single electron in their outermost shell, which makes them highly reactive, especially with water. Group 2 elements, known as alkaline earth metals, include beryllium, magnesium, calcium, strontium, barium, and radium. These elements have two electrons in their outer shell and are also reactive, though less so than alkali metals.
The trend in reactivity of Group 7 elements (halogens) is opposite to that of Group 1 elements (alkali metals) due to their differing electron configurations and tendencies to gain or lose electrons. Group 1 elements have one electron in their outer shell and readily lose it to achieve a stable electron configuration, making them highly reactive. In contrast, Group 7 elements have seven electrons in their outer shell and tend to gain an electron to complete their octet, which makes them more reactive as you move up the group. Therefore, while reactivity increases down Group 1, it increases up Group 7.
Group 17 elements are reactive because they only need to gain one electron to achieve a stable electron configuration with a full outer shell (octet). This makes them highly reactive as they readily react with other elements to gain that one extra electron and achieve a stable state.
