Why is fluorine a stronger oxidizing agent than chlorine?
fluorine is more powerful oxidising agent than chlorine. it is mainly because of the following two reasons Bond dissociation enthalpy of F2 is less than that of Cl2. Electron gain enthalpy of F2 is less than that of Cl2. F- has high hydration enthalpy than Cl- due to small size.
Why is Florine more electronegative than chlorine?
The larger pull from the closer fluorine nucleus is why fluorine is more electronegative than chlorine is. As the halogen atoms get bigger, any bonding pair gets further and further away from the halogen nucleus, and so is less strongly attracted towards it.
Why is fluorine the most reactive metal?
What toothpaste do most dentists recommend?

Why do some noble gases react with fluorine?
Universe
- during type II supernovae, bombardment of neon atoms by neutrinos could transmute them to fluorine;
- the solar wind of Wolf–Rayet stars could blow fluorine away from any hydrogen or helium atoms; or
- fluorine is borne out on convection currents arising from fusion in asymptotic giant branch stars.

Why fluorine is reactive than chlorine?
Electronegativity is probably the biggest thing that plays into reactivity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.Feb 16, 2017
Why is chlorine less reactive than fluorine?
(ii) The valence shell of chlorine (Cl = 2, 8, 7) is M-shell (n = 3). Its radius is large. Its tendency to gain an electron is small as compared to fluorine. Therefore, chlorine is less reactive than fluorine.Mar 12, 2022
Is fluorine more reactive than chlorine?
The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react.
Why fluorine is the most reactive?
Being an element of the group $17$ fluorine tends to form polar covalent bonds with non-metal. Eg: $H - F$. Having a $ - 1$ oxidation state fluorine can also form an ionic bond. Hence, Fluorine is the most reactive of all the halogens due to its small size.
Why is fluorine more reactive than fluorine?
Reactivity is an elements ability to gain an electron. So the better it is at "stealing" electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.May 10, 2020
Why does fluorine have lower electron affinity than chlorine?
Electron affinity of fluorine is less than that of chlorine because the atomic size of fluorine is very less than chlorine as a results there is a large electronic repulsion between the electrons of fluorine.Mar 12, 2022
Why is fluorine the most reactive halogen GCSE?
This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. For this reason, fluorine is the most reactive halogen and astatine is the least reactive of the halogens.
Why is fluorine more reactive than other elements?
Fluorine is the most reactive element among halogen. This is due to the minimum value of F-F bond dissociation energy. Hence fluorine is more reactive than other halogens.Mar 12, 2022
Why is fluorine called most reactive nonmetal?
Fluorine is the most reactive non-metal because it is the most electronegative of all of the non-metal elements of the periodic table. Due to its strong electro negativity & small size, Fluorine has a strong tendency to accept electrons from other atoms or ions. As a result it oxidises all other substances.
Why is fluorine more electronegative than chlorine?
Fluorine is more electronegative than chlorine because fluorine is smaller and has its electrons closer to the positively charged nucleus. ...
Why is fluorine more reactive than chlorine?
Fluorine is more reactive. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and others and thus more strongly attracted. Fluorine is most electronegative, thus it is most reactive.
Which is more reactive, fluorine or bromine?
The smallest Halogens are best at doing this: so Fluorine is more reactive than Chlorine, which is more reactive than Bromine, which is more reactive than Iodine, which would be more reactive than Astatine.
Which element is the second most reactive?
Since electronegativity decreases going to the left of the periodic table, oxygen is the second most reactive element on the list. Metalloids are generally less reactive than metals and nonmetals. Correspondingly, why fluorine is reactive than chlorine?
Which is smaller, fluorine or chlorine?
Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, between the nucleus and the electron again makes it more likely to attract the electron and react to gain a noble gas configuration.
Which has fewer electron shells than chlorine?
Fluorine also has fewer electron shells than chlorine, so there are fewer electrons between the positive nucleus and the reacting electron to essentiallly block, or weaken, the electromagnetic attraction. This is shielding. Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, ...
What are the three things to consider every single time relative reactivity is unknown?
971. There are three things to consider every single time relative reactivity is unknown; atomic radius, shielding, and number of electrons. The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role.
Which halogen has more electrons?
The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react.
What is the reactivity of organic S N 1?
In the context of organic S N 1 reactions, the reactivity is R − F (least) < R − C l < R − B r < R − I (most). [1] This reflects the leaving group ability, with larger atoms better able to accommodate the extra electron.
Is fluorine a noble gas?
This is shielding. Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, between the nucleus and the electron again makes it more likely to attract the electron and react to gain a noble gas configuration. Reactivity is an elements ability to gain an electron.
Is fluorine more reactive than chlorine?
Electronegativity is probably the biggest thing that plays into reactivity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive. Fluorine molecule has a small atomic radius with 5 electron in 2p orbital. This means it has a high charge density on its atom.
