Highly reactive because they only have 7 electrons. They need 8 to be a stable element.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
Halogens
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
they need one more electron to attain noble gas configuration and hence are highly reactive.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
Group 18, also called the noble gases, contains the elements that are nonreactive.
group 1 elements are stored in oil because they are highly reactive elements.
Halogens
Halogens these are the salt forming elements which are highly reactive
Halogens these are the salt forming elements which are highly reactive
Because they are highly reactive with many other elements.

they need one more electron to attain noble gas configuration and hence are highly reactive.
Group 7 elements are halogens. They have seven valance electrons& are highly reactive. They are: -Fluorine -Chlorine -Bromine -Iodine
Magnesium is highly reactive and will react with many things. It will react with elements of the Nitrogen group, the Oxygen group and the halogens. It will also react with acids, water etc.
