The middle ages begin with the fall of the western half of Roman Empire in 476
Answer:
It is a negative ion that has one more valence electron than a neutral bromine atom.
Explanation:
The bromine atom (Br) accepts one electron and forms the bromide ion (Br-), which carries a unit negative charge. Thus, the charge of the bromide ion is -1.
Bromine is corrosive to human tissue in a liquid state and its vapors irritate eyes and throat. Bromine vapors are very toxic with inhalation. Humans can absorb organic bromines through the skin, with food and during breathing. Organic bromines are widely used as sprays to kill insects and other unwanted pests.
Its salts are found in the crust at about . 4 parts per million. Bromine is only the 64th most common element on Earth. It is more rare than three quarters of the elements that comprise the Earth's crust
bromine is commonly found in highly un-reactive bromide salts - in much the same way that the poisonous green gas chlorine is commonly found in boring sodium chloride, table salt. ... Today, bromine is extracted on an industrial scale from salt lakes that are especially rich in the element, above all the Dead Sea
To get jobs in factories, down mines etc. The Agricultural Revolution had led to enclosures of land, which m eant that many people could no longer earn a living from the country. The small farms that used to support most people were replaced by large farms belonging to a smaller number of landowners. The small farmers were driven out to look for work elsewhere. Some of them became farm labourers, working for the big farmers instead of running their own small farms. Others went to the towns.
The industrial revolution brought about a massive change in the way people worked for everyone, not just the small farmers. Prior to the revolution, most people worked in or near their own homes. Crafts like spinning, weaving, pottery etc were carried out at home, not in factories. Whole families tended to be involved in whatever the family enterprise might be. The Industrial Revolution obliged people to go and work in factories instead of working at home. The home and the workplace had become irrevocably seperate. People no longer worked for themselves, but for other people.
