The video tutorial explains two methods to determine the number of valence electrons for radon (Rn). The first method involves using the periodic table, where radon is identified as a noble gas with eight valence electrons. The second method uses the electron configuration, confirming radon has eight valence electrons by examining the highest energy level. The tutorial also briefly covers drawing the Lewis structure for radon, emphasizing its eight valence electrons.
