well, there is no group 7a, but thats kind of a hard one to answer, because some groups have the same amount of reactive metals. The actinide and lanthinide series both have a large amount of reactive subsances. But those are series.

Does group 7A of the periodic tables contain the least reactive nonmetals?
The halogen group is the MOST reactive nonmetal group.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
What element is most reactive in the group 7a?
flourine, reactivity goes down group 7Florine (F)
Are Group 7A elements the alkaline earth metals?
Group 7A are not metals.Alkaline earth metals refer to Group 2A.and group 7a is halogens which are non-metals
Does group 7A of the periodic table contain the most reactive nonmetal?
Yes. Using the modern numbering system, that group is named group 17. Group 17 contains the halogens, the most reactive nonmetals.
The highly reactive elements in group 7A which are known for forming salts are the?
Halogens
Which group are highly reactive non metals on the periodic table?
The more reactive elements on the periodic table are farther down in the rows. For example, Te, or Tellurium, is in group 16 and row 5. The elements in row 7 are the most reactive, but technically Tellurium, since it is the farthest down nonmetal on the periodic table, would be the most reactive nonmetal, technically making group 16 the most reactive row of the nonmetals.
What element group are extremely reactive nonmetals?
"Halogens"Group 7A on the Periodic Table.Fluorine and everything straight below it.
What is the maost reactive non-metal family?
The halogens or group 7A elements. They are the most reactive non-metal family because they only need one more valence electron to have a complete octet.
Which group of elements reliably forms acids when combined with hydrogen?
Group 17 (7A), the halogens.
Where are the most reactive nonmetals located?
The most reactive nonmetals are the Halogens. They are located in the second to last row on the periodic table from the right.
What group of elements easily gains one valence electron?
Generally speaking, the metals give away electrons during a reaction. Not all metals are equally reactive, however. The metals of group 1 (the alkali metals) all have 1 valence electron. This 1 electron is given away very easily, making this group the most reactive of all the metals. They are so reactive, in fact, that these elements do not exist by themselves; only in compounds.
