Discription and explain the formation of positive and negative ions

when an atom loses an electron it gets a net positive charge on it and become positive in, and when atom gain an electron it receives a net negative charge on it and becomes a negative ion

Explanation:

the right answer is c i just did the question.

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.
