How do you calculate the #of protons neutrons and electrons?
First you need to look up the element on a periodic table of elements. I am sure you have one laying around somewhere =P Anyway, then look in the square that contains your element for a number either in the upper left corner or in some cases directly above it. That is the number of protons in the atom. Then you also know the number of electrons which is exactly the same as the number of protons. To figure out neutrons, look for another number on in the square that isnt in the left corner or above the element. This is the atomic mass.
