Answer:
Not much heat moves into the lower levels of the ground. The heat that the ocean absorbs is mixed with the lower water quickly. ... At night, while the land cools off quickly, the water at the surface is kept warmer because the water is mixed around with the warmer water underneath.
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.
<span>When an ionic bond is formed between sodium (na) and chlorine (cl), the resulting molecule is called halite (salt). Ionic bonds involve the transfer of valence electrons. When this occurs between metals and non-metals, the metal loses an electron (becoming a cation) and the non-metal gains an electron (becoming an anion).</span>
