Bromine: geological information

Bromine is never found as the free element, but always as the bromide, Br-. The usual source is some natural brines and there are few minerals consisting largely of bromide.

Abundances of bromine in various environments

In this table of abundances, values are given in units of ppb (parts per billion; 1 billion = 109), both in terms of weight and in terms of numbers of atoms. Values for abundances are difficult to determine with certainty, so all values should be treated with some caution, especially so for the less common elements. Local concentrations of any element can vary from those given here an orders of magnitude or so and values in various literature sources for less common elements do seem to vary considerably.

Abundances for bromine in a number of different environments. Use the links in the location column for definitions, literature sources, and visual representations in many different styles (one of which is shown below)
Location ppb by weight ppb by atoms
Universe 7 0.1
Sun no data no data
Meteorite (carbonaceous) 1200 230
Crustal rocks 3000 780
Sea water 67300 5210
Stream 20 0.3
Human 2900 230


Log abundance (by atom numbers) in our sun

The chart above shows the log of the abundance (on a parts per billion scale) of the elements by atom number in our sun. Notice the "sawtooth" effect where elements with even atomic numbers tend to be more strongly represented than those with odd atomic numbers. This shows up best using the "Bar chart" option on the chart.
