How are additional electrons accounted for when writing Lewis dot structures for ions?
Options
- ABy subtracting them from the total number of valence electrons
- BBy adding them to the total number of valence electrons
- CBy ignoring them
- DBy doubling the valence electrons
Correct answer
B. By adding them to the total number of valence electrons
Step-by-step solution
For anions, each negative charge would mean addition of one electron, and for cations, each positive charge would result in subtraction of one electron from the total number of valence electrons.
