Question

c. How many total valence electrons are not bonding for the central atom in the molecule of sulfur dioxide? none, 1, 2, 3, 4

Answer 1

Answer:

2

Explanation:

Since Sulphur atom has 6 valence electrons...in which when forming a sulphur dioxide molecule...it uses 4 valence electrons...in which the sulphur atom shares its electrons...in an order of 2 electrons per each oxygen atom

Hence leaving 2 valence electrons...which are not used
