assign me two large second-semester general chemistry classes for the spring. In this video, we will discuss the trends in the properties of group-17 elements, such as the negative electron gain enthalpy, oxidation states, oxidising power of halogens etc.Ġ1:27 - Trends in the atomic properties like atomic size, ionisation enthalpy and electronegativity.Ġ1:32 - Trends in the negative electron gain enthalpyĠ4:31 - Trends in the oxidising power of halogens. For example, a typical chemistry undergrad probably knows more chemistry, in the academic sense, than most highly productive post-docs at the best schools in the world. When I saw the TED presentation on Khan Academy (Khan, 2011), I thought.
