Nitrogen is found in nature as n2, or diatomic nitrogen. one nitrogen atom typically has 5 valence electrons. when n and n combine to form n2, there is a triple bond that forms. how many unpaired electrons remain as a result? none a total of 2, one on each n a total of 4, two on each n a total of 6, 3 on each n

None. as the first electron shell holds 2 and the sceond holds 8
