What was the origin of name of bromine?

Answer 1

It's extracted from brine - salty water from lakes like the dead sea.

Unfortunately brine, being denser than water, sits at the bottom of the lake, and the only way to access it is via a water-tight mineshaft built from shore out under the lake.

These mines, even with todays health and safety standards, are very dangerous to operate. It's not uncommon for the North-Jordan bromine mine to have 10-20 casualties per year.

As such, people who work in these mines often form a close-knit community and consider other workers like family, or 'bros'.

Thus, bromine mines have for the longest time been known as 'bro-mines', which is where the name comes from, as it was mined some hundred years before anyone know what it was and what to call it.
