Chemistry Practice Problems: How to Write Electron Configurations and Identify Periodic Trends

In this video I show you how to write electron configurations, how to identify trends in atomic size, how to classify elements by type (main group vs. transition), and how to draw dot formulas. You should pause the video and try to answer these yourself before proceeding to check your answers.

Chemistry lectures and "How to" videos from a university professor and Ph.D. chemist. I live stream office hours every week and discuss the latest news in climate change, space travel, and the intersection of science and politics. Come join the Melko Lab and learn by osmosis!
