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?

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 is fluorine the most reactive?
the valence bonding is seen close to the nucleus hence the attraction for a new electron is greater and can gain an extra electron more easily.
Why is fluorine more reactive than chlorine ks3?
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.
Why is Cl less reactive than F?
chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to gain an electron than it is for a fluorine atom.
Why the element fluorine is more reactive than the other halogens?
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 F2 more reactive than Cl2?
F2 is more reactive than Cl2 due to greater repulsion in the non-bonded electron pairs in the molecule of F2 as compared to Cl2 therefore the bond cleavage in fluorine becomes easier. In group 17 of the periodic table, fluorine is more reactive than chlorine, and chlorine is less reactive than fluorine. Give reasons.
How is fluorine reactive?
fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.
Is fluorine more stable than chlorine?
hence , Fluorine is more stable than Chlorine. also , there is a rule that states , more negative charge on more electronegative atom is always a stable atom. Electronegativity of fuorine is greater than chlorine and fluorine is also having Negative charge making it more stable than Chlorine.
Is fluorine the most reactive element?
Among the halogens, fluorine, chlorine, bromine, and iodine, fluorine is the most reactive one. It forms compounds with all other elements except the noble gases helium (He), neon (Ne) and argon (Ar), whereas stable compounds with krypton (Kr) and xenon (Xe) are formed.
Why fluorine is the most reactive element in Group 7?
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.
What makes fluorine so reactive?
So the better it is at "stealing" electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. Electro negativity is the tendency of an atom to attract a shared pair of electrons.
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.
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.
Why is fluorine more reactive than chlorine?
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 has more electrons, chlorine or fluorine?
Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react. 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.
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.
Why is chlorine less reactive than fluorine?
For example chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. 967 views · Answer requested by. Shubham Katyal. Related Answer.
How many electrons does flour have?
Flourine has a total of 9 electrons, 2 in the first and 7 in the second. Those 7 electrons are tightly bound to the nucleus because they are so close. The atom has a very strong affinity ( degree in which a substance will bind to something) to get the missing 8th electron needed to have a full shell.
What is the role of electron configuration in reactivity?
Electron configuration is also responsible for reactivity, as the electron configuration can tell you if an atom needs to gain or lose electrons, so the closer an atom is to filling up a shell, the more it wants an electron, and therefore the more reactive it is. For metals, they are. Continue Reading.
Which element has the highest electron affinity?
Despite being less electronegative than oxygen and fluorine, chlorine has the highest electron affinity of any element. Also oxygen is normally found in its triplet state which has a barrier to reacting with singlet species (most organic compounds). Singlet oxygen is more reactive than chlorine I believe.
Which element is the most electronegative?
Fluorine is the most electronegative element on the periodic table, which means that it is a very strong oxidizing agent and accepts other elements' electrons. Fluorine 's atomic electron configuration is 1s22s22p5. Fluorine is the most electronegative element because it has 5 electrons in it's 2P shell.
Is fluorine stronger than chlorine?
Generally Fluorine is, by quite a lot. Although Chlorine has a higher electron affinity (not by very much though) Fluorine is a much stronger oxidant under standard conditions, this is due to the anomalously weak F-F bond, high hydration enthalpy (due to small size and charge density of F − ), and high lattice energy, ...
Is fluorine more reactive than chlorine?
This allows fluorine atoms to take electrons more easily than chlorine atoms, and so fluorine is more reactive than chlorine.
