What is the total number of valence electrons in an azide ion,N₃-?

Question

Quizplus · Accepted Answer

Each nitrogen atom contributes 5 valence electrons (group 15 of the periodic table) and there is a negative charge present, which adds 1 additional valence electron. Therefore, the total number of valence electrons in an azide ion is 3 x 6 + 1 = 19. However, we need to consider that the ion has an overall charge of -1, which means we need to add 1 more electron to the total, resulting in 20 valence electrons.
