**Understanding Group 2 Metal Bonding**

When Group 2 metals bond with nonmetals or polyatomic ions, it's essential to understand the nature of electron transfer. Students often encounter questions like the following to deepen their comprehension of chemical bonding:

**Key Question:**
- What question would a student need to know to form a compound with Group 2 metals?

**Options:**
1. Will Group 2 elements gain electrons to bond with nonmetals in Group 16 in a 2:1 ratio?
2. Will Group 2 elements lose electrons to bond with nonmetals in Group 17 in a 1:2 ratio?
3. Will Group 2 elements gain electrons to bond with nonmetals in Group 17 in a 1:2 ratio?
4. Will Group 2 elements lose electrons to bond with nonmetals in Group 16 in a 2:1 ratio?

**Exploring the Options:**
- **Option 1** and **Option 3** suggest that Group 2 elements gain electrons, which contradicts their nature as metals (which typically lose electrons).
- **Option 2** suggests the correct process where Group 2 elements lose two electrons, allowing them to bond with nonmetals in Group 17, resulting in a 1:2 stoichiometric ratio.
- **Option 4** incorrectly associates Group 2 metals with losing electrons to Group 16 nonmetals in a 2:1 ratio.

Understanding these options helps clarify the typical bonding behavior of Group 2 metals when forming compounds.
