What is the total number of valence electrons in an isocyanate ion,NCO-?

Question

Quizplus · Accepted Answer

To find the total number of valence electrons in NCO-, we need to add up the valence electrons of nitrogen, carbon, and oxygen atoms and then subtract one electron to account for the negative charge of the ion.

Nitrogen has 5 valence electrons, carbon has 4 valence electrons, and oxygen has 6 valence electrons. Adding these together, we get:

5 + 4 + 6 = 15

Subtracting one for the negative charge, the total number of valence electrons in NCO- is:

15 - 1 = 14

Therefore, the correct answer is (C) 16.
