This graph shows the relationship between the electron binding energy, atomic number, and electron configuration. As you move left to right within a period, the ionization energy of an element generally increases.
A whole set of periodic table trends worksheets covering everything from ionization energy, electronegativity, atomic radius, ionic radius, reactivity, and all other trends covered in a traditional high school chemistry class. Each page has students color in or draw arrows to indicate the trend and each page includes questions to help students focus on the "why" behind each trend! Science with Mrs. Lau
