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
Answer:
Postwar recovery that imposed harsh standards on the Southern states and supported newly freed slaves (freedmen) in their pursuit of political, economic, and social opportunities.
Lack of workers was not a problem that cities faced during the Gilded Age.
Archaeological evidence indicates that civilization emerged in the Indus Valley around 3300
BCE. Over two millenniums, the inhabitants of this northwestern region of the Indian
subcontinent developed into a prosperous civilization with a distinct cultural style. However,
around 1500 BCE, a new culture, the Aryans, entered India through the Khyber Pass, and
began integrating themselves into the social framework of the Indus Valley civilization.
The origin of the Aryan people is subject to continuous scholarly debate; however, two theories
prevail. Traditionally, it has been thought that the Aryans emerged in the Caucasus region and
migrated westward into Europe and eastward into India. Another theory, the Cultural Diffusion
Hypothesis, states that the Aryans originated in the Indus Valley.
The Aryans furnished civilization in the Indian subcontinent with many impressive cultural and
religious contributions and shaped Indian society for thousands of years with the creation of the
caste system.
Society
According to traditional theories, the Indian caste system has its origins in the advent of the
Aryans in the Indus Valley. Thus, this social stratification system was the product of the Aryan
people’s will to separate themselves from, and subjugate, the local populations.
Initially, this new society, which included Aryans and non-Aryans, was hierarchically divided into
four varnas (i.e. castes). In fact, these four original varnas could be better categorized in two
groups: Aryans and Non-Aryans. Nevertheless, the four varnas, from the top down, were: the
Brahmins—Aryans (priests, scholars, and philosophers); the Kshatriyas—Aryans (rulers and
warriors); the Vaishyas—Aryans (farmers, traders, merchants, and craftsmen); and the lowest
caste, the Shudras—non-Aryans (laborers, peasants, and servants for the other castes).
Each varna was divided into jatis (i.e. sub-castes), which identified the individual’s occupation
and imposed marriage restrictions. Marriage was only possible between members of the same
jati (or two that were very close).
Both varnas and jatis determined a person’s purity level. Members of higher varnas or jatis had
higher purity levels, and if contaminated (even by touch) by members of lower social groups,
they would have to undergo extensive cleansing rites.
