When bromine reacts to form an ion, it becomes isoelectronic with krypton. Both bromine (Br) and krypton (Kr) have 36 electrons in their neutral state. When bromine gains one electron to form the Br- ion, it now also has 36 electrons like krypton.

Does Bromine react with air?

Yes, bromine reacts with air to form bromine vapors. Bromine reacts with oxygen present in the air to form bromine oxides.


Does bromine form an ion isoelectronic with krypton?

No, bromine forms an ion with a charge of -1. An ion isoelectronic with krypton would have the same number of electrons as krypton, which is 36 electrons.


Aluminum metal reacts with bromine gas?

Aluminum metal reacts with bromine gas to form aluminum bromide. This is a redox reaction where aluminum is oxidized and bromine is reduced. The balanced chemical equation for this reaction is 2Al + 3Br2 -> 2AlBr3.


Can nitrogen and bromine form ionic or non ionic compounds?

Nitrogen and bromine can form both ionic and nonionic compounds. When nitrogen reacts with bromine, it can form covalent compounds such as nitrogen tribromide (a nonionic compound). However, under certain conditions, nitrogen and bromine can also form ionic compounds, such as when nitrogen reacts with bromine to form the ionic compound ammonium bromide.


What is bromine reaction with water?

Bromine reacts with water to form a mixture of Hydrobromic Acid, HBr, and Hypobromous Acid, HBrO.


Does bromine react to sodium?

Yes, bromine reacts with sodium to form sodium bromide. This reaction is a displacement reaction where bromine replaces another element in a compound.


What happens when ethanol reacts with bromine water?

When ethanol reacts with bromine water, the bromine is displaced by the oxygen in ethanol, resulting in decolorization of the bromine water. This reaction occurs because ethanol is a reducing agent, which means it can donate electrons to the bromine atoms, converting them from a colored form (brown/red) to a colorless form.


What is the reaction of sodium and bromine?

When sodium reacts with bromine, they form sodium bromide. This is a redox reaction where sodium loses an electron to bromine, which gains an electron to form the bromide ion. The reaction is highly exothermic and can be violent if not controlled.


What does bromine commonly react with?

Bromine commonly reacts with alkali metals, such as sodium, potassium, and magnesium, to form ionic compounds called metal bromides. It also reacts with alkenes to form dibromo compounds through addition reactions. Additionally, bromine can react with organic compounds to substitute hydrogen atoms with bromine atoms in a process called bromination.


Citral reacts with bromine dissolved in water?

Citral reacts with bromine dissolved in water to form a dibrominated product. This reaction involves the addition of bromine across the carbon-carbon double bond in the citral molecule. Dibrominated citral is formed as a result of this halogenation reaction.
