Chapter 1.4
Reading the Periodic Table: Trends, Valence Electrons, and Ions
The periodic table is not a list; it is a map of how hard each atom holds its outer electrons. Read the map and you can predict which elements grab electrons, which give them up, and what ions they form.

By the end
- 01Explain trends in radius, ionization energy, electron affinity, and electronegativity with shielding and effective nuclear charge
- 02Estimate a missing property value from a column or row neighbor
- 03Predict the typical ionic charge of an element from its valence electron count
- 04Explain why elements in one column form analogous compounds
