Which of the following statements best describes the current atomic theory? Question 14 options:

Electrons are evenly distributed throughout a mixture of positive and neutral particles.

Electrons exist in specific energy levels but we cannot predict their exact location or velocity.

Electrons are held in an atom by their attraction to each other

Electrons move in circular motion around the nucleus.

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.
