Difference Between Bromine and Iodine

Bromine and iodine are halides; in other words, they are chemical elements found in group 17 of the periodic table of elements. The key difference between bromine and iodine is that bromine is a liquid at room temperature while iodine is a solid at room temperature.

Is iodine stronger than bromine?

Similarly, bromine is a more powerful oxidizing agent than iodine. Bromine can remove electrons from iodide ions, producing iodine; iodine cannot reclaim those electrons from the resulting bromide ions.

Is iodine better disinfectant than chlorine?

Overall, the disinfection effectiveness of iodine is not as heavily influenced by pH as chlorine is. Hypochlorite (OCl-) formation increases at pH values > 7.

Why is iodine less reactive than bromine?

Iodine has 5 shells whereas bromine has 4 shells. Since bromine has less number of shells, the outer shell is closer to the nucleus and there is a strong force of attraction between the positive charge of the nucleus and the electrons in the outermost shell.

Can bromine be used as a disinfectant?

Bromine substances are disinfectants and can be used as an alternative for chlorine. In swimming pools, bromine is used against the formation and growth of algae, bacteria and odors in swimming water. In the United States, bromine has been used since 1936 to treat swimming water.

Does iodine displace bromine?

Bromine only displaces iodine from potassium iodide and the least reactive iodine cannot displace chlorine or bromine from their salts.

What type of bond is bromine and iodine?

Sodium loses its valence electron to become stable, and iodine gains an electron in its outermost shell. Each atom follows the octet rule. c) Bromine and bromine form covalent bonds because bromine is a non-metal and each atom must share electrons in order to satisfy the octet rule.

Do iodine tablets kill viruses?

Iodine water purification tablets are really only effective against viruses and bacteria, and more appropriate as a second stage purification method to kill viruses after removing giardia and cryptosporidium with a water filter.

What is the disadvantage of iodine?

Excessive iodine consumption can lead to similar symptoms as iodine deficiency, including thyroid dysfunction and goiter. Too much iodine may lead to thyroiditis and thyroid papillary cancer. At very high levels, iodine poisoning can cause: burning of the mouth, throat, and stomach.

Is Iodine a good disinfectant?

Iodine is an effective disinfectant for viruses, bacteria, and many cysts at IWPD manufacturer- recommended iodine dosages and contact times. In general, iodine is most effective against bacteria, followed by viruses.

Is iodine more or less reactive than bromine?

Bromine is more reactive than iodine, but not as reactive as chlorine.

Why is iodine not very reactive?

Iodine is the least reactive of the halogens as well as the most electropositive, meaning it tends to lose electrons and form positive ions during chemical reactions.

Which is more reactive bromine or fluorine?

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.
