Download Station #1: Chemistry

Station #1: Chemistry Sodium and chlorine will form an ionic bond because both are naturally unstable. Diagram the process below. 1. How many electrons does sodium have? 11 2. How many protons does sodium have? 11 3. What is the overall charge of sodium? 0 (neutral) 4. How many electrons does chlorine have? 17 5. How many protons does chlorine have? 17 6. What is the overall charge of chlorine? 0 (neutral) 7. Draw the electrons of each atom below. Use an arrow to show which atom will lose/gain an electron. e‐ e‐
