The first three excited states of the nucleus au-199 (gold) are at 0.075 mev, 0.320 mev and 0.475 mev. if all transitions between theses states and the ground state occurred, what energy gamma rays would be observed? note: be sure to consider all possible transitions.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
