Questions: Which atoms could combine to form an ionic compound? Silver and calcium Sulfur and chlorine Silver and phosphorus Hydrogen and sulfur

Solution Steps

Ionic compounds are formed when atoms transfer electrons from one to another, resulting in the formation of positively charged cations and negatively charged anions. Typically, this occurs between metals and non-metals.

1. Silver and calcium: Both are metals, so they are unlikely to form an ionic compound.
2. Sulfur and chlorine: Both are non-metals, so they are unlikely to form an ionic compound.
3. Silver and phosphorus: Silver is a metal and phosphorus is a non-metal, so they could potentially form an ionic compound.
4. Hydrogen and sulfur: Hydrogen is a non-metal and sulfur is also a non-metal, so they are unlikely to form an ionic compound.

From the analysis, the pair that could combine to form an ionic compound is silver and phosphorus.
