When the surface of moon reflects light from the sun, it results in shining of moon and regardless the fact that sometimes moon seems to shine brightly, the moon reflects between 3 to 12 percent of the sunlight which hits it.

Answer:
Four

Explanation:
Calcium Sulfide is an ionic compound made up of Ca²⁺ and S²⁻.
Ca²⁺ is formed as,

Ca → Ca²⁺ + 2 e⁻

These two electrons are accepte by Sulfur as,

S + 2 e⁻ → S²⁻

So, before accepting 2 electrons S was having six valence electrons, after accepting two electrons from Ca it has 8 electrons which are present in four pairs as shown below,
