What is the Difference Between Bromine and Iodine?
🆚 Go to Comparative Table 🆚Bromine and iodine are both halogens found in group 17 of the periodic table of elements. They share some similarities, but there are key differences between them:
- Physical State: Bromine is a liquid at room temperature, while iodine is a solid at room temperature.
- Atomic Number: Bromine has an atomic number of 35, while iodine has an atomic number of 53.
- Melting Point: Bromine has a melting point of -7.2°C, while iodine has a melting point of 113.7°C.
- Boiling Point: Bromine has a boiling point of 58.8°C, while iodine has a boiling point of 184.4°C.
- Reactivity: Bromine is more reactive than iodine but less reactive than chlorine.
- Oxidizing Agent: Bromine can remove electrons from iodide ions, producing iodine, while iodine cannot.
Both elements have 7 valence electrons and are composed of nonmetals. They share a -1 oxidation state, are less reactive than fluorine and chlorine, and have a similar electronic configuration.
