How many electrons are there in #Br^-#?

1 Answer

  • Element Bromine (Br), Group 17, Atomic Number 35, p-block, Mass 79.904. Elements are organised into blocks by the orbital type in which the outer electrons are.
  • An atom of bromine is atomic number 35, so it has 35 protons and 35 electrons. Following the order of orbital filling predicted by the Aufbau principle, the electron configuration for bromine is.
  • Bromine is an active ingredient in four products; two products with multiple active ingredients and two products as the sole active ingredient. The multiple active ingredient products control mold, mildew, fungi, insects, and odors in exposed surfaces of bedding, mattresses, textiles, drapes, upholstered furniture, rugs, carpets, and storage areas.

Hydrobromic acid (HBr 3) Sodium bromate (NaBr) Interesting facts. It is obtained from sea water. It is a strong irritant that in concentrated forms can cause skin blisters. Approximately 500 million kilograms of bromine are produced worldwide in a year. Brominated vegetable oil.

Electrons

Explanation:

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.

Bromine

Below is the Lewis dot structure for a neutral bromine atom, which has seven valence electrons.
Below is the Lewis dot structure for a #'Br'^(-)'# ion, which has eight valence electrons. The extra valence electron gives it a negative charge.
