What type of reaction is bromine and sodium?
2Na + Br2. 2NaBr Sodium react with bromine to produce sodium bromide. This reaction takes place at a temperature of 150-250°C.
What would happen if you reacted sodium with bromine?
Reactions with sodium Hot sodium will also burn in bromine or iodine vapor to produce sodium bromide or sodium iodide. Each of these reactions produces an orange flame and a white solid.
Is iodine less reactive than bromine?
Bromine is more reactive than iodine, but not as reactive as chlorine.
What happens when chlorine reacts with bromine?
When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide. The solution turns brown. This brown colour is the displaced bromine.
Is iodine smaller than bromine?
Originally Answered: Why is iodine less reactive than bromine? Both Br and I are halogens, so both have 7 electrons in their outermost shell. The difference is that iodine is a considerably larger atom, so the additional electron would go into a shell which is further removed from the positively charged nucleus.
Is Iodine a reducing agent?
The iodide ion is a strong reducing agent; that is, it readily gives up one electron. Although the iodide ion is colourless, iodide solutions may acquire a brownish tint as a result of oxidation of iodide to free iodine by atmospheric oxygen.
Does bromine oxidize iodine?
Chlorine, Bromine and Iodine Bromine can only oxidize iodide ions, and is not a strong enough oxidizing agent to convert chloride ions into chlorine. A red solution of iodine is formed (see the note above) until the bromine is in excess.
What are 3 factors that affect atomic size?
The actual trends that are observed with atomic size have to do with three factors. These factors are: the number of protons in the nucleus (called the nuclear charge). the number of energy levels holding electrons and the number of electrons in the outer energy level.
What are the trends for atomic size?
Periodic Trend The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.
What are the factors that influence the size of the atom?
The actual trends that are observed with atomic size have to do with three factors. These factors are: The number of protons in the nucleus (called the nuclear charge). The number of energy levels holding electrons (and the number of electrons in the outer energy level).
What is smaller mg or Mg2+?
Answer. So Mg atom will be larger as it has more electrons than Mg 2+ and thus will have larger atomic radii.
