If you are taking finasteride to treat BPH, you should know that finasteride may control your condition, but will not cure it. It may take at least 6 months before your symptoms improve. Continue to take finasteride even if you feel well. Do not stop taking finasteride without talking to your doctor.
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons. 15 people found this useful.
The small size of subatomic particles is perhaps most convincingly expressed not by stating their absolute units of measure but by comparing them with the complex particles of which they are a part. An atom, for instance, is typically 10 â10 metre across, yet almost all of the size of the atom is unoccupied âemptyâ space available to the point-charge electrons surrounding the nucleus.
