Question

potassium and oxygen will react to form an ionic compound. part 1 of 2 write the formula of the compound formed. part 2 of 2 write the name of the compound formed.

Explanation:

Step1: Determine ion charges

Potassium (K) is in Group 1, so it forms a $K^+$ ion with a +1 charge. Oxygen (O) is in Group 16, so it forms an $O^{2 - }$ ion with a - 2 charge.

Step2: Balance charges

To balance the charges in an ionic compound, we need 2 potassium ions for every 1 oxygen ion. So the formula is $K_2O$.

Step3: Name the compound

The cation is potassium and the anion is oxide. The name of the compound is potassium oxide.

Answer:

Part 1: $K_2O$
Part 2: Potassium oxide
