flourine, reactivity goes down group 7
Florine (F)
Group 7A or halogens. The most reactive element is fluorine.
Group VIIA or group 17 or halogens: The most reactive element in this group is Fluorine.
it is about F2 gas. It is the most reacivated gas.
The most reactive element in the group 7 is manganese.
Oxygem
fluorine
Yes. Using the modern numbering system, that group is named group 17. Group 17 contains the halogens, the most reactive nonmetals.
If you mean group 7A, the element that is a liquid at room temperature is bromine.
They would form an ionic compound.
The compound in group 7A and third period is Bromine or Br. The dot of this would be . . :Br. . . The compound in group 7A and third period is Bromine or Br. The dot of this would be . . :Br. . .
This is a consequence of the law of periodicity of chemical elements.
"Halogens"Group 7A on the Periodic Table.Fluorine and everything straight below it.
The halogen group is the MOST reactive nonmetal group.
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.
Yes. Using the modern numbering system, that group is named group 17. Group 17 contains the halogens, the most reactive nonmetals.
Halogens
From group 17 (7A), fluorine has the lowest atomic radius.
If you mean group 7A, the element that is a liquid at room temperature is bromine.
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
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.
Iodine is itself an element. It is in group 7a. A compound that it is in for instance is potassium iodide
The most reactive nonmetals are the Halogens. They are located in the second to last row on the periodic table from the right.
There is no Group 14. The elements of the group 7A are the most electronegative. Basically, electronegativity is the ability to attract electrons. Group 7A elements, or halogens, need just one more electron to reach stability, and are very reactive. So, they can easily accept that electron. In other words, their ability to attract electrons is the highest.
