Graph 1: electronegativity (on y-axis) versus atomic number (on x-axis) Graph 2: first ionization energy (on y-axis) versus atomic number (on x-axis) Graph 3: atomic radius (on y-axis) versus atomic number (on x-axis) On each graph, use a connected line between data points. Also, the title of each graph must also include your initials.

Ne has the highest I.E. because it has the highest effective nuclear charge and uses the lowest number of energy levels. e. Si, P, N Si has the lowest I.E. because it has the lowest effective nuclear charge and is tied (with P) for using the most energy levels.
