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.
No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
Yes. Using the modern numbering system, that group is named group 17. Group 17 contains the halogens, the most reactive nonmetals.
The nonmetals in Group 7A are called halogens. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive elements that tend to form salts when they react with metals.
"Halogens"Group 7A on the Periodic Table.Fluorine and everything straight below it.
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.
The highly reactive elements in group 7A, also known as group 17 or the halogens, are fluorine, chlorine, bromine, iodine, and astatine. These elements are known for forming salts by gaining an electron to achieve a full outer electron shell.
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
The classification with 1A, 7A etc. is not recommended by IUPAC and is obsolete.The 1A elements are alkali metals, all solids; the 7A elements are the nonmetals (halogens). Halogens can be gaseous, liquids or solids at room temperature.
Fluorine and the rest of the group are known as "Halogens" (salt-formers, literally)
