For nitrogen, the nucleus would look something like this: Step 4 - Place the Electrons. This atomic number was eventually identified as the charge of the nucleus or the number of electrons surrounding an atom which is almost always found in a neutral, or balanced, state. Thus, a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and eight neutrons, although the two masses will be different. Answer: C. 5 3. To avoid confusion, electrons emitted by the nucleus are referred to as beta particles. Orbiting around the nucleus are even smaller particles called electrons. The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral ch certain particles play and important role in the transfer of force, the bosons or force carriers the use of virtual particles to carry force resolves the action at a distance problem Bosons are the particles which transmits the different forces between the matter particles, they normally have a whole number spin, 0, 1 or 2.
