Explore the fundamental concept of how changing a single proton in an atom's nucleus can drastically alter its elemental properties in this 14-minute educational video. Delve into the relationship between protons, electrons, and chemical behavior, understanding why elements are classified by proton count rather than electron number. Examine the role of quantum mechanics in determining electron configurations, and discover how energy considerations and the law of entropy influence atomic structure. Learn about the formation of elements through stellar fusion processes and gain insights into why not all elements exhibit noble gas stability.
