Question

I am not sure if I have the ones right that I already did.  Thanks! 

**Lesson 9: Exit Ticket**

**Magnesium Chloride (MgCl₂):** A source of magnesium needed for nerve and muscle function, keeping our heartbeat steady, and supporting a healthy immune system.

- **Lewis Diagram for Mg:**
  - "Mg" with two dots representing the valence electrons.

- **Lewis Diagram for Cl:**
  - "Cl" with seven dots around it, showing valence electrons.

- **Model for MgCl₂:**
  - This section seems to be intended for illustrating how magnesium bonds with two chlorine atoms, forming MgCl₂.

**Question:**
How does placement on the Periodic Table explain why 1 Mg atom bonds with 2 Cl atoms to form MgCl₂?

**Prompt:**
Develop a claim using the evidence from your models to answer the question: What state of matter would you expect to find this substance in "the Goldilocks Zone"? Why? Refer back to the melting and boiling point data from the previous lesson to help you.
