What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why? an ionic bond because there is less than a 0.4 difference in electronegativity between the atoms

a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms

a nonpolar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms

oh it is true if thats what you are asking

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.
