Valence Electrons in XeH4

Dr. B explains how to draw the Lewis structure for XeH4. Xenon has 8 valence electrons, and each of the four hydrogens has 1, totaling 12 valence electrons. Xenon is placed in the center with hydrogens around it. Initial bonds use 8 electrons, filling hydrogen's outer shells. Xenon can hold more than 8 electrons, so the remaining 4 are added to it. This completes the structure, ensuring all valence electrons are used. The formal charges confirm this is the best structure for XeH4.
