Question

question 1
what is the sum of valence electrons in sulfur dioxide? (so₂)
18 v.e.
24 v.e.
12 v.e.
20 v.e.

Explanation:

Step1: Determine valence electrons of sulfur

Sulfur (\(S\)) is in group 16 of the periodic table, so it has \(6\) valence electrons.

Step2: Determine valence electrons of oxygen

Oxygen (\(O\)) is also in group 16, so each oxygen atom has \(6\) valence electrons.

Step3: Calculate total valence electrons in \(SO_{2}\)

In \(SO_{2}\), there is \(1\) sulfur atom and \(2\) oxygen atoms.
The total valence electrons \(=6+(2\times6)=6 + 12=18\)

Answer:

18 v.e.
