Practice question · Numerical answer
How many valence electrons must a Lewis structure of the carbonate ion, , account for in total?
Hints
- Add the valence electrons of every atom, then adjust for the charge.
- Carbon gives 4, each oxygen 6, and the 2- charge adds 2 more.
Show the answer
24
Why
from the atoms, plus 2 for the charge, giving 24 valence electrons to place.
