How do halogens react with other elements?
How do halogens react with other elements?
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride….Reactions with metals.
| Halogen | Reaction |
|---|---|
| Chlorine | Hot iron wool burns vigorously to produce orange-brown iron(III) chloride |
Why do halogens react with noble gases?
Explanation: Halogens are very reactive because they have seven valence electrons and need one more to have eight valence electrons (an octet). They react with metals and other halogens to get an octet. When this happens, the atoms become stable and have noble gas configurations.
Why are the halogens very reactive?
Due to their high effective nuclear charge, halogens are highly electronegative. Therefore, they are highly reactive and can gain an electron through reaction with other elements.
Why do the halogens Group 17 react quickly and easily with the alkali metals group 1 to form salts?
Using electron configuration, explain why the halogens readily react with the alkali metals to form salts… They easily lose valence electrons and form compounds such as sodium chloride. Why is an iron alloy, such as steel, preferred over pure iron? They tend to be harder, stronger, and more resistant to corrosion.
Why is f2more reactive than O2?
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. Fluorine has a smaller atomic radius than oxygen.
Why CIF is more reactive than cl2?
F atom is small in size. (b) Although electron gain enthalpy of fluorine is less negative as compared to chlorine, fluorine is a stronger oxidising agent than chlorine .
Which element is more reactive oxygen or sulfur?
oxygen is only more reactive than sulphur because due to small atomic size oxygen atom has high tendency to attract the electrons ( more electronegative )….
Does sulfur act like oxygen?
Because sulfur is much less electronegative than oxygen, it is more likely to form compounds in which it has a positive oxidation number (see table below). In theory, sulfur can react with oxygen to form either SO2 or SO3, whose Lewis structures are given in the figure below.
Is sulfur a better nucleophile than oxygen?
Sulfur is a larger atom than oxygen, making its electrons more polarizable. Thus, it is a stronger nucleophile than oxygen.
Is sulfur a good Electrophile?
On other hand, the electronegativity of sulphur is quite less. Hence, it can donate electrons more easily compared to oxygen. The substance which donates a lone pair of electrons to a Lewis Acid is called an ELECTROPHILE. Thus, sulphur is more nucleophilic than oxygen.
Why is fluorine a bad Nucleophile?
Hydrogen Fluoride is not one of the strong acids. It’s a weak base… The affinity it has for hydrogen is what makes it a poor nucleophile. It would rather grab a hydrogen and leave than attack an electrophilic site.
Why Sulphur is less basic than oxygen?
Oxygen is more electronegative atom than sulfur. More the electronegative means that the electrons attraction tendency is more. However, the sulfur atom is less electronegative than oxygen. Hence, removal of sulfur atom is easy.
