Are Bromide Ions Positive or Negative?

Ionic substances contain charged particles called ions . For example, lead bromide contains positively charged lead ions and negatively charged bromide ions.

Is bromine a positive or negative ion?

The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron. The extra valence electron gives it a negative charge.

What is the charge of bromide ion?

A bromide is a chemical compound containing a bromide ion or ligand. This is a bromine atom with an ionic charge of −1 (Br⁻); for example, in caesium bromide, caesium cations (Cs⁺) are electrically attracted to bromide anions (Br⁻) to form the electrically neutral ionic compound CsBr.
