What group of elements on the periodic table are very reactive and why?

Group 1 elements are most reactive. The want desperately to have an octet of electrons but they have 1 too many (or 7 too few depending on how you look at it). And they will do anything to ionize to get that octet. They also get more reactive the larger they get. This is why the smaller halogens which lack a single electron (they are pretty reactive too) are not quite as reactive and why K is more reactive than Na. (NB: Atoms get larger moving down a group and smaller moving from left to right across a period).

∙ 12y agoThe alkali metals and the halogens are the most reactive because they only need to lose/gain one electron, respectively, to have a full valence (ie a noble gas configuration).

Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Which group on the Periodic Table of Elements has the most reactive nonmetals?
group 17 or halogens
If you were looking for a very reactive atom would you look in group 1 or 18?
The most reactive chemical elements are in the first group of the periodic table of elements.
What is the least reactive groups on the periodic table?
Noble gases are least reactive because they have a full shell
Are the most reactive metals in the middle of the periodic table?
No the most reactive metals are in the first group on the periodic table. They get more reactive as you go down a group
Are the elements on group 17 on the periodic table reactive?
Yes
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Which group on the Periodic Table of Elements has the most reactive nonmetals?
group 17 or halogens
What are the non-reactive and reactive elements in periodic table?
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.
What group of elements on the periodic table is most reactive?
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
If you were looking for a very reactive atom would you look in group 1 or 18?
The most reactive chemical elements are in the first group of the periodic table of elements.
What are the elements in group 8 called on the periodic table?
Halogens these are the salt forming elements which are highly reactive
What are elements called in the periodic table in Group one?
Halogens these are the salt forming elements which are highly reactive
Where are the most reactive metals grouped in the periodic table of elements?
Group I, the Alkalai Metals
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.
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Which elements are most likely to react with other elements?
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.
