### Chemical Reactions and Ion Formation #### Understanding Ion Formation The image above illustrates the formation of ions following a chemical reaction. Two atoms are shown undergoing a transfer of electrons, which results in the creation of charged particles known as ions. From left to right: 1. **Initial State**: The first pair of diagrams shows two neutral atoms; the left atom has one electron in its outer shell while the right atom lacks one electron to complete its outer shell. 2. **Electron Transfer**: An arrow indicates the transfer of a single electron from the left atom to the right atom. This transfer leads to the formation of new charged states for both atoms. 3. **Final State**: The final pair of diagrams shows the two newly formed ions; the left atom now has one less electron (forming a cation with a positive charge), and the right has one additional electron (forming an anion with a negative charge). #### Question Analysis **Question:** *What results from the chemical reaction illustrated above?* **Answer Options:** - ○ a cation with a net charge of +1 - ○ a cation with a net charge of -1 - ○ an anion with a net charge of +1 - ○ an anion with a net charge of -1 - ○ a cation with a net charge of +1 and an anion with a net charge of -1 **Explanation:** The chemical reaction depicted illustrates a single electron being transferred from the left atom to the right atom. Consequently: - The left atom loses an electron and gains a net positive charge (forming a cation, \( \text{charge} = +1 \)). - The right atom gains an electron and gains a net negative charge (forming an anion, \( \text{charge} = -1 \)). Thus, the correct answer to the question "What results from the chemical reaction illustrated above?" is: - ○ a cation with a net charge of +1 and an anion with a net charge of -1
