which image depicts the initial atoms when calcium and sulfur form an ionic compound? a. ca s b. ca s c. ca s

Answer:

B. Ca .S

Explanation:

Step1: Analyze calcium valence electrons

Calcium (Ca) is in Group 2, has 2 valence - electrons shown as 2 dots around Ca.

Step2: Analyze sulfur valence electrons

Sulfur (S) is in Group 16, has 6 valence - electrons shown as 6 dots around S.

Step3: Determine initial state

In the initial state before the formation of an ionic compound, the atoms are separate and show their valence electrons. Image B shows Ca with 2 valence electrons and S with 6 valence electrons in their initial, non - bonded state.
