How many valence electrons in NO2?

Answer 1

In N: 2+5(= valence) = 7 electrons

In 3*O: 3*[2+6(= valence)] = 24 electrons

In negative ion charge (-1) = 1 electron

In total 32 ( = 7 + 3*8 + 1 ) of which 5 + 3*6 + 1 = 24 valence electrons in (12) covalent bonds (12 pairs).

Answer 2

How many valence electrons are there in NO3-?

Answer 3

NO3 or nitrate ion has a negative charge. So the total number of valence electrons is 24: 5 electrons for N, 6 times 3 for O, and 1 for the extra negative charge.

Answer 4

NO3 has a charge of -2. It gains 2 electrons. So the answer is 6.

Answer 5

there are 18 valence electrons in NO2-

Answer 6

24
