2 Points What charge would an ion have if it had more electrons than protons?
A. It would be neutral, since electrons would be outside the nucleus.
B. It would have no charge.
C. It would have a net negative charge.
D. It would have a net positive charge.

C, negative

Explanation: Electrons give a negative charge, so having more electrons then postiivley charged protons would result in a negative charge.

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.
