Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.

How many electrons does bromide ion have?
The element bromine has an atomic number of 35. This means that each atom contains 35 protons, and the requirement for electrical neutrality in an atom means that the atom also contains 35 electrons. A bromide ion contains one more electrons than a bromine atom: 36.
Why does chlorine displace bromine from potassium bromide solution?
Fundamentally, because this reaction reduces the Gibbs free energy of the reactants when they are converted to products. Chlorine atoms have substantially greater electronegativity than bromine atoms, while chloride and bromide ions both have about the same, very low, electronegativity. Therefore, chemical potential energy is reduced by removing an electron from each bromide ion to form a bromine atom and transferring the electron so removed to chlorine atoms to form chloride ions instead of bromide ions.

Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
Why bromine does not react with aqueous potassium chloride?
Chlorine is more reactive than bromine thus bromine is unable to displace chlorine to form potassium bromide.
What is the charge on BrCl3?
The Bromide atom has a charge of -1. Bromide is found is seawater--thusly, seafood and seaweed have higher sources of bromide than most any other food. Bromide salts are also used extensively in medicine, particularly veterinary sciences.
Which is larger an arsenic ion or a bromine ion?
An arsenide ion is larger than a bromide ion, but a bromide ion is larger than an arsenic ion. Recall that arsenic can have several oxidation states. It can be a cation or an anion.
Is a chlorine atom larger than a bromine?
Chlorine is in 3rd period and 17th group bromine is in 4th period and 17th group. The number of shells present in an atom is equal to the period no. In which it is present. So, chlorine has 3 shells while bromine has 4 shells. And atomis size is the distance between centre of nucleus and outermost shell. So, bromine atom is larger than bromine atom..

Why chlorine displaces bromine from potassium bromide?
Chlorine is a stronger oxidizing agent than bromine.
Why can't iodine be used to displace bromine from sodium bromide?
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
What will displace bromine from aqueous calcium bromide?
Something more reactive than bromine. Chlorine or fluorine would do it.
Aluminum bromide plus chlorine yields aluminum chloride and bromide?
Yes. Chlorine is more reactive than bromine.
Is Br a larger atom than C?
Chlorine is in 3rd period and 17th group bromine is in 4th period and 17th group. The number of shells present in an atom is equal to the period no. In which it is present. So, chlorine has 3 shells while bromine has 4 shells. And atomis size is the distance between centre of nucleus and outermost shell. So, bromine atom is larger than bromine atom..
