Cause if it were inside the nucleus it wouldn't be an orbit. the electron has to maintain a certain amount of energy to resist the eletro-static force of the opposite charge of the nucleus. The...
It is more accurate to say that electrons move randomly around the nucleus, and statistically they can be found in specific regions, or clouds, with a known probability. An orbit (such as a satellite...
It depends on the atomic number. For example, to find the number of electrons in carbon, look at a periodic table. You will see that the atomic number for carbon is 6, so 6 electrons orbit a carbon...
