Valence Electrons in XeCl3-

The video tutorial explains how to draw the Lewis structure for XeCl3-. It begins by counting the valence electrons for xenon and chlorine, considering the negative charge. Xenon is placed at the center due to its lower electronegativity, with chlorine atoms surrounding it. Valence electrons are used to form bonds and complete the octets for chlorine. Xenon, being an exception to the octet rule, accommodates extra electrons. The tutorial concludes with a complete Lewis structure, highlighting xenon's ability to hold more than eight electrons.
