Answer;
it wants to take on another electron
Fluorine has seven electrons in its outer energy level. According to the octet rule, it wants to take on another electron.
Explanation;
-The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
-Therefore, fluorine which has seven electrons requires to gain one electron to have eight electrons in the outermost energy level, making it stable (octet). In other words fluorine reacts by gaining one electron.
Answer:
it wants to take on another electron
Explanation:
Two cities, in particular, have been excavated at the sites of Mohenjo-Daro on the lower Indus, and at Harappa, further upstream. The evidence suggests they had a highly developed city life; many houses had wells and bathrooms as well as an elaborate underground drainage system. The social conditions of the citizens were comparable to those in Sumeria and superior to the contemporary Babylonians and Egyptians. These cities display a well-planned urbanization system.
There is evidence of some level of contact between the Indus Valley Civilization and the Near East. Commercial, religious, and artistic connections have been recorded in Sumerian documents, where the Indus valley people are referred to as Meluhhaites and the Indus valley is called Meluhha. The following account has been dated to about 2000 BCE: "The Meluhhaites, the men of the black land, bring to Naram-Sin of Agade all kind of exotic wares." (Haywood, p. 76, The Curse of Agade)
The Indus Civilization had a writing system which today still remains a mystery: all attempts to decipher it have failed. This is one of the reasons why the Indus Valley Civilization is one of the least known of the important early civilizations of antiquity. Examples of this writing system have been found in pottery, amulets, carved stamp seals, and even in weights and copper tablets.
Another point of debate is the nature of the relationship between these cities. Whether they were independent city-states or part of a larger kingdom is not entirely clear. Because the writing of the Indus people remains undeciphered and neither sculptures of rulers nor depictions of battles and military campaigns have been found, evidence pointing in either direction is not conclusive.
By 1800 BCE, the Indus Valley Civilization saw the beginning of their decline: Writing started to disappear, standardized weights and measures used for trade and taxation purposes fell out of use, the connection with the Near East was interrupted, and some cities were gradually abandoned. The reasons for this decline are not entirely clear, but it is believed that the drying up of the Saraswati River, a process which had begun around 1900 BCE, was the main cause. Other experts speak of a great flood in the area. Either event would have had catastrophic effects on agricultural activity, making the economy no longer sustainable and breaking the civic order of the cities. Hope This Helps!:)
