Elaborate on the nuclear model of the atom. The nuclear model describes the atom as protons and neutrons distributed throughout a sea of electrons. The nuclear model describes the atom as electrons uniformly scattered in a positive cloud of protons. Eliminate The nuclear model describes the atom as a small, negative center enveloped by a cloud of positive particles. The nuclear model describes the atom as a dense, positive nucleus surrounded by a cloud of negative electrons.

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
