The halogens (group 17) gets less and less reactive as you go down the group. With Flourine being the most resctive and then the others below it becoming less reactive (not to say the others arent reactive though)

What is the symbol of the element in group 7 and period 5?
The element is Technetium with the symbol, Tc.
What element is in group 7 and has 5 energy shells?
That would be iodine (I).
Which group of nonmetals is the most reactive in soild phase?
Group 7. Fluorine, which belongs to group 7, is the most reactive element.
What group does group one from the periodic table likes to reacts with?
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
What element is most reactive in the group 7a?
flourine, reactivity goes down group 7Florine (F)
