Lithium has a 1+ charge, and oxygen has a 2- charge. A Lewis dot diagram should contain one lithium atom and two oxygen atoms to show how these form an ionic bond. True or false?

false

because it does not have the potential to be entirely used up

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
