+5
B
+3
C
0
D
-3

Verified step by step guidance1
Recall that the oxidation number of hydrogen in most compounds is +1.
Let the oxidation number of nitrogen in NH_3 be x.
Write the equation for the sum of oxidation numbers in the molecule NH_3, which must equal zero because the molecule is neutral: \(x + 3(+1) = 0\).
Simplify the equation to find \(x\): \(x + 3 = 0\).
Solve for \(x\) to find the oxidation number of nitrogen.
