In this video, we look at group 0 elements, which are also called the noble gases. First we look at the electronic structure of group 0 elements and see how they all have a full outer energy level (electron shell). We then see how this makes the group 0 elements generally unreactive. Next we look at the trend in boiling points of the group 0 elements and see why they are all gases at room temperature.
