To solve the question, we need to fill in the blanks with the appropriate words from the given options. 1. **Identify the composition of diamond:** - Diamond is an allotrope of carbon. In its crystal structure, diamond consists of carbon atoms that are arranged in a tetrahedral lattice. - Therefore, the first blank should be filled with "atoms." 2. **Identify the composition of calcium chloride:** - Calcium chloride (CaCl2) is an ionic compound composed of calcium ions (Ca²⁺) and chloride ions (Cl⁻). ...
