It isn't. Fluorine is more reactive. However, Chlorine is more reactive than Bromine, Iodine and Astatine. It is all to do with molecular size. Fluorine wants to get to a stable 10 electrons to be like Neon more than Chlorine wants to get to get 18 lectrons to be like Argon. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and thus more strongly attracted.

What metal is very chemicaly reactive?
Metals are highly reactive because of their characteristic electronic configuration, that is, the electrons in the atoms of metals have high tendency to leave their respective atoms and react with other species which have high tendency to accept electron.
Why alkaline and halogens are so reactive?
Alkaline and halogens are reactive because usually they are attracted to each other. Why? Because halogens have seven valence electrons, or electrons in their outermost shell, while alkaline metals only have one valence electron. An example of a halogen is florine and chlorine. An alkaline metal example is hydrogen and lithium.
What do halogens iodine and chlorine have in common?
Halogens are very reactive nonmetals because their atoms need to gain only one electron to have a complete outer level. The atoms of halogens combine readily with other atoms, especially metals, to gain that missing electron. The reaction of a halogen with a metal makes a salt, such as sodium chloride. Both chlorine and iodine are used as disinfectants. Chlorine is used to treat water. Iodine mixed with alcohol is used in hospitals.Although the chemical properties of the halogens are similar, the physical properties are quite different,
When added to water what element produces acid?
Chlorine & other halogens.
Which ellement can replace all other halogens from the solution of their salts?
Fluoirine
What makes halogens stand out from all of the other elements?
They are highly reactive
What two things react with lithium?
Lithium is a highly reactive metal, so it can react with many other ions, especially halogens such as fluorine, chlorine, bromine, and iodine
Why are halogens found in nature only in coumpounds?
Halogens such as fluorine or chlorine are HIGHLY reactive; they always undergo chemical reactions with other elements to form compounds. It's almost impossible to find pure samples of any halogen gas.
Why fluorine an chlorine have similar reactivities?
Fluorine and chlorine both show similar chemical behaviors because they are both in the same family, the Halogens, which are all highly reactive gases with 7 valence electrons. Ie, They will bond to other chemicals in the same way.
What elements on the table are most reactive why?
Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy. Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.

What is the name of the halogen that is in period 3?
The halogen that is in period 3 of the periodic table is chlorine (Cl). Chlorine is a member of Group 17 (Group VIIA), also known as the halogens. Other members of this group include fluorine (F), bromine (Br), iodine (I), and astatine (At). Chlorine is a highly reactive nonmetal and is commonly found in compounds such as sodium chloride (table salt).
Why can't the halogen group be found free in nature?
It is because halogens are some of the most reactive elements in existence Every atom wants to have a full valence outer shell. Halogens are only missing one electron to have a full valence shell. So either they are diatomic halogens such as chlorine which never is singular it is either Cl2 or mixed with other elements.
Chlorine is a highly reactive gas?
Yes, it directly combines with many other elements to form compounds in their highest oxidation state.
How does iodine differ from other halogens?
Iodine is solid and less reactive.
