What halogen reacts violently with sodium?
The reaction between sodium and a halogen becomes less vigorous down the group. Fluorine reacts violently with sodium at room temperature.
How does fluorine react with sodium?
While not a normal route of preparation because of the expense, sodium metal reacts vigorously with all the halogens to form sodium halides. So, it burns with fluorine, F2, to form sodium(I) fluoride, NaF.
What happens when chlorine reacts with sodium?
If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.
Do Group 7 elements react with metals?
Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’.
When halogens react with metals they form salts called what?
The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts. The halogens all have the general electron configuration ns 2 np 5 , giving them seven valence electrons.
What happens when halogens react with metals and nonmetals give example?
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride. The halogens become less reactive going down group 7….Reactions with metals.
| Halogen | Reaction |
|---|---|
| Iodine | Hot iron wool reacts slowly in iodine vapour to produce grey iron(II) iodide |
Which halogens can be displaced by fluorine?
Option d (all halogens can be displaced by fluorine) is the correct answer. In single displacement reactions, more reactive elements displace less…
When sodium combines with fluorine to make sodium fluoride What is the formula?
How sodium metal and fluorine gas combine to form sodium fluoride base on this equation 2Na(s) + F_2(g) rightarrow 2NaF(s)? Study.com.
Which halogen would react with sodium chloride?
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride. The halogens become less reactive going down group 7. The reaction of sodium with fluorine will be more vigorous than the reaction between sodium and chlorine.
What type of reaction can be used to place the halogens in order of reactivity?
displacement reactions
They also undergo redox reactions with metal halides in solution, displacing less reactive halogens from their compounds. These displacement reactions are used to establish an order of reactivity down Group 17 of the periodic table.
Do halogens react with non-metals?
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride. The halogens become less reactive going down group 7….Reactions with metals.
| Halogen | Reaction |
|---|---|
| Fluorine | Cold iron wool burns to produce white iron(III) fluoride |
How do halogens react with metals to produce salts?
The halogens react with metals to produce salts (the word ‘halogen’ means ‘salt former’). For example, chlorine reacts with sodium: Sodium + chlorine → sodium chloride 2Na (s) + Cl2(g) → 2NaCl (s)
Why do the halogens have similar chemical properties?
This means that the halogens all have similar chemical properties. The halogens react with metals to produce salts (the word ‘halogen’ means ‘salt former’). For example, chlorine reacts with sodium:
How do Group 7 elements react with metals and hydrogen?
They react with metals to form metal halides, and with hydrogen to form acidic hydrogen halides. Reactivity decreases down the group. Atoms of group 7 elements all have seven electrons in their outer shell.
What do halogens have in common with Group 7 elements?
Atoms of group 7 elements all have seven electrons in their outer shell. This means that the halogens all have similar chemical properties. The halogens react with metals to produce salts (the word ‘halogen’ means ‘salt former’).
