Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Electron Configuration of Potassium
- Electron dot structure: $$\bullet K
- Potassium (K) is in Group 1 (alkali metals) - Atomic number is 19 - Potassium wants to lose its single valence electron
Step 3:: Electron Configuration of Chlorine
- Electron dot structure: $$Cl \bullet\bullet\bullet\bullet\bullet
- Chlorine (Cl) is in Group 17 (halogens) - Atomic number is 17 - Chlorine wants to gain one electron to complete its octet
Step 4:: Electron Transfer
- Chlorine becomes $$Cl^{-}$$ (anion)
- Chlorine gains this electron - Electron transfer creates ions:
Step 5:: Ionic Bonding
- Resulting ionic compound: $$K^{+}Cl^{-}
- The transferred electron creates an ionic bond - The electron dot structure shows complete electron transfer
Final Answer
- Ions present: Potassium cation (K^{+}) and Chloride anion (Cl^{-}) - Compound formed: Potassium chloride (KCl)
