If you are taking finasteride to treat male pattern hair loss, it may take at least 3 months before you see any improvement because hair loss and growth happen slowly over time. However, you should expect to see improvement during the first 12 months of your treatment.
1 Electrons-Subatomic particle that has almost no weight and carries a negative charge; orbits in a shell about the nucleus of an atom. 2  Neutrons-Subatomic particle that has a weight of one atomic mass unit, carries no charge, and is found in the nucleus of an atom.
To this point all molecules have had an overall charge of zero, however, this is not the case with polyatomic ions. poly = many. atomic = atoms. ion = charged particle. Soâ¦polyatomic ion means a molecule of multiple atoms that have a charge. Polyatomic ions are stable. The ions are found in solutions or solids where the overall charge of the solid is zero or the solution is zero. What this means is that you can not have a test tube full of Na+ and no negative charges like a chloride (Cl-1) to cancel out the overall positive charge.
