Valence Electrons in ASO3 3- Ion

The video tutorial explains the process of constructing the Lewis structure for ASO3 3-. It begins by detailing the valence electrons of Arsenic and Oxygen, and the additional electrons due to the -3 charge. The tutorial then guides through placing the Arsenic atom at the center, surrounded by Oxygen atoms, and forming chemical bonds. It ensures the octet rule is satisfied for each atom, using all 26 valence electrons. The video concludes with a review of the completed structure, confirming that all atoms have full valence shells.
