Which of the following set of quantum numbers can match an electron in the 3d orbital? n = 3, l = 3, ml = 0 n = 3, l = 2, ml = -3 n = 2, l = 3, ml = -2 n = 3, l = 2, ml = -2

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

answer; 4 electrons;

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.
