Finasteride is in a class of medications called 5-alpha reductase inhibitors. Finasteride treats BPH by blocking the body's production of a male hormone that causes the prostate to enlarge. Finasteride treats male pattern hair loss by blocking the body's production of a male hormone in the scalp that stops hair growth.
The electron is a subatomic particle, symbol eâ or Î²â, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.
Maximum number of electrons in an energy level. Each energy level of an atom could only accomodate a certain number of electrons. The maximum number of electrons that can populate a certain energy level is given by the following formula.where n = the specific energy level. 1  The maximum number of electron in the first energy level (n = 1) is 2 (1) 2 = 2 electrons. The maximum number of electron in the fifth energy level (n = 5) is 2 (5) 2 = 50 electrons. 2  The maximum number of electron in the sixth energy level (n = 6) is 2 (6) 2 = 72 electrons. 3  The maximum number of electron in the seventh energy level (n = 7) is 2 (7) 2 = 98 electrons.
