Ionization Energy, Electron Affinity, Atomic Radius, Ionic Radii, Electronegativity, Metallic Character

Explore the fundamental concepts of periodic trends in chemistry through this comprehensive video tutorial. Learn about first ionization energy, electron affinity, atomic radius, ionic radii, electronegativity, and metallic character. Discover how these properties change across the periodic table and understand the underlying principles that govern these trends. Examine the effects of nuclear charge, electron shielding, and quantum mechanics on atomic properties. Practice with numerous examples and problems to reinforce your understanding of topics such as effective nuclear charge, Coulomb's law, isoelectronic species, and the differences between metals and nonmetals. Gain insights into the exceptions to periodic trends and learn how to predict and compare properties of elements and ions based on their position in the periodic table.
