Question

28
what is the total number of electrons in the correct lewis dot formula of the sulfite ion? *

8
24
32
26
30

Explanation:

Step1: Determine valence electrons of each atom

Sulfur (S) has 6 valence electrons. Oxygen (O) has 6 valence electrons. The sulfite ion is \(SO_{3}^{2 -}\). There is 1 S atom and 3 O atoms.

Step2: Calculate total valence electrons

Valence electrons from S: \(6\times1 = 6\). Valence electrons from O: \(6\times3=18\). The ion has a charge of \(2-\), so we add 2 more electrons.
Total electrons \(=6 + 18+ 2=26\)

Answer:

26
