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.
Polyatomic ions: Polyatomic ions are electrically charges collections of two or more atoms. Typically in beginning classes people are not expected to predict polyatomic ion formulas. Polyatomic ions usually have a charge because the collection of atoms has either gained an extra electron or else it has lost an electron.Most of the common inorganic polyatomic ions have negative charges.This means the ion has more electrons than the neutral atoms that are in the ion.A polyatomic ion like phosphate, PO43- has three extra electrons beyond the electrons on the P and O atoms.ost of the common inorganic polyatomic ions have negative charges.
