Approved Tutor Answer10 Months agoThe bromide ion, represented as Br⁻, has gained an extra electron compared to its neutral state. To determine the number of electrons in Br⁻, we first look at the atomic number of bromine, which is 35. This means a neutral bromine atom has 35 electrons.
Calculating Electrons in Br⁻
Since Br⁻ has one additional electron due to its negative charge, we add this to the number of electrons in a neutral bromine atom:
- Electrons in neutral Br: 35
- Additional electron in Br⁻: +1
Therefore, the total number of electrons in Br⁻ is:
35 + 1 = 36 electronsSummary
In summary, the bromide ion (Br⁻) contains a total of 36 electrons.
