Fluorine is most reactive of the three because it has the highest electronegativity (highest tendency to attract an electron towards itself). Fluorine is in fact the most electronegative element in the entire Periodic Table. The reactivity of the halogens decrease down the group.
Fluorine is more reactive.
due to its small size and high electronegativity
What else can I help you with?
What has the most metallic character fluorine chlorine bromine or iodine?
Fluorine has the most metallic character among fluorine, chlorine, bromine, and iodine. Metallic character decreases as you move across a period from left to right on the periodic table, and fluorine is the first element in the halogen group.
Why was chlorine isolated before fluorine?
Chlorine was isolated before fluorine because it is more reactive and abundant, which made it easier to isolate and study. Fluorine is the most reactive of all elements and is rarely found in its elemental form in nature, making it more challenging to isolate.
Most reactive nonmetals?
The most reactive nonmetals are located in Group 17 of the periodic table, known as the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive due to their strong tendency to gain electrons to achieve a full outer electron shell.
Which of the element chlorine fluorine iodine and br is the strongest oxidizing agent?
Fluorine is the strongest oxidizing agent among the elements chlorine, fluorine, iodine, and bromine. It has the highest electronegativity and is most effective at accepting electrons in a redox reaction.
Why is chlorine more reactive than bromine?
Chlorine is more reactive than bromine because it has a smaller atomic radius and higher effective nuclear charge, leading to stronger attraction for electrons. This makes it easier for chlorine to gain electrons and achieve a stable electron configuration through the formation of ionic or covalent bonds. Additionally, the higher electronegativity of chlorine compared to bromine also contributes to its greater reactivity in chemical reactions.
What is the most reactive chlorine bromine fluorine and helium?
Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.
Which is the third most reactive halogen?
Bromine (Br2) is the third most reactive halogen.
What are the top three most reactive halogen's?
Fluorine, Chlorine, and Bromine in order of decreasing activity.
Which family of nonmetals is most reactive?
The halides (Group VII): fluorine, chlorine, bromine, & iodine.
Name the most reactive family of non-metals?
Halogens: fluorine, chlorine, bromine, iodine, astatine.
Which is the second most reactive halogen?
Chlorine is the second lightest member of the halogen elements or group 17.
What is the most reactive non-metal?
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
What are the most reactive nonmetals in the halogenes?
First of all, all halogens are non-metals. Secondly, the most reactive is fluorine, which reacts to nearly everything, hence it is rare. After fluorine comes chlorine, then bromine and iodine.
Which of the two halogens shown is more reactive?
The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.
Which group contains the most reactive non metals?
The Halogens are most reactive non-metals. They have the most tendency to accept electrons in their respective periods. The Halogen family comprises of Fluorine, Chlorine, Bromine, Iodine and Astatine
What group on the periodic table is the most reactive nonmetals?
Group 17, otherwise known as the halogens; fluorine, chlorine, bromine, iodine and astatine.
What are the most reactive nonmetals located on the periodic table?
The most reactive metals are located at the left top of the periodic table. Fluorine is the most reactive non metal. The next two members are oxygen and chlorine.Fluorine, chlorine and bromine are highly reactive. They easily gain electron. They are present in group-17.
