how many valence electrons are in the sulfite ion so$_{3}^{2 - }$?
how many valence electrons are in the sulfite ion so$_{3}^{2 - }$?
Answer
Explanation:
Step1: Determine valence electrons of S
Sulfur (S) is in Group 16, has 6 valence electrons.
Step2: Determine valence electrons of O
Oxygen (O) is in Group 16, each O has 6 valence electrons. There are 3 O atoms, so total from O is 6×3 = 18.
Step3: Account for the charge
The ion has a 2 - charge, which means 2 extra electrons.
Step4: Calculate total valence electrons
Add up electrons from S, O and the extra electrons: 6+18 + 2=26.
Answer:
26
