Nobel · Answer 1

The model you are describing is of a Helium atom because of the atomic number. In the atom's nucleus should be the two neutrons and protons and there should be one outer layer with the two electrons on it. You can determine it's location and electron count/number of outer layers through looking at the periodic table. Helium is in period 1 which determines how many outer layers it has.
