Chapter 3: Problem 105

How many electrons are there in Br'? What \(1+\) cation has the same number of electrons as Br"?

Short Answer

Expert verified
The Br^(-) ion has 36 electrons. The 1+ cation with the same number of electrons is Br^(+).

Step by step solution

01

Find the atomic number of Bromine

To find the number of electrons in a Br^(-) ion, first, we should know the atomic number of Bromine. The atomic number of Bromine (Br) is 35, which represents the number of protons and electrons in a neutral atom.
02

Determine the number of electrons in Br^(-) ion

Since the ion has a -1 charge, it means it has gained one additional electron compared to a neutral Br atom. Therefore, the total number of electrons in a Br^(-) ion is the atomic number of Bromine (35) plus the extra electron from the negative charge: 35 + 1 = 36 electrons
03

Find a 1+ cation with the same number of electrons

We are looking for an ion with a +1 charge and 36 electrons. To find this ion, we need a neutral atom that has one less electron than Br^(-). A neutral atom with 35 electrons has an atomic number of 36 - 1 = 35. The element with an atomic number of 35 is Bromine (Br). If Bromine loses one electron, it will have a +1 charge and the same number of electrons as a Br^(-) ion. So the 1+ cation with 36 electrons is Br^(+).
