Hw 2B 5b

Postby Baoying Li 1B » Thu Oct 31, 2019 4:35 pm

For this problem, I got 21 for the number of valence electrons of NHF2. But the answer shows only 20 valence electrons. I wonder if I calculated the number of valence electrons wrong?

I think it might've just been a minor calculation error. Here's what I got:

NHF2
N: 5 valence electrons
H: 1 valence electron
F: 7 valence electrons * 2 = 14 valence electrons

Total = 5 + 1 + 14 = 20 valence electrons
