Diagramas de Configuración Electrónica

The video tutorial explains the basics of atomic structure, focusing on electron configurations. It covers how electrons are arranged in shells around the nucleus, using lithium as an example. The tutorial outlines the rules for filling electron shells, including the maximum number of electrons each shell can hold. It also provides a practical exercise for drawing the electron configuration of a carbon atom, emphasizing the importance of understanding electron distribution in atoms.
