Studdy Solution
STEP 1
1. Potassium (K) is a metal.
2. Iodine (I) is a non-metal.
3. Ionic compounds are typically formed between metals and non-metals.
STEP 2
1. Identify the elements involved and their typical bonding nature.
2. Determine the correct chemical formula for the compound formed.
3. Classify the type of bond in the compound.
STEP 3
Potassium (K) is a metal, and iodine (I) is a non-metal. Metals and non-metals typically form ionic bonds.
STEP 4
When potassium reacts with iodine, they form potassium iodide. The chemical formula for potassium iodide is KI.
STEP 5
Since KI is formed from a metal (potassium) and a non-metal (iodine), it is an ionic compound.
The correct description of the compound is:
They form the compound KI, which is ionic.
