Worksheet 4 - Periodic Trends A number of physical and chemical
... When an electron is removed from an atom the repulsion between the remaining electrons decreases. The nuclear charge remains constant, so more energy is required to remove another electron from the positively charged ion. This means that, I1 < I2 < I3 < ..., for any given atom. Going down a group t ...

... just: you don’t want to have two electrons in the same space at the same time. Again, that’s a very loose analogy, but that’s more or less what it’s saying physically: each electron must have its own set of quantum numbers that uniquely describes where it is. This allows us to understand the helium ...
