Question

potassium chloride is a salt held together by ionic bonds. answer the following questions about potassium chloride. (hint use the periodic table.) what is the charge on the potassium ion? select what is the charge on the chloride ion? select how many potassium ions are in one molecule of potassium chloride? select how many chlorine ions are in a molecule of potassium chloride? select

Explanation:

Step1: Determine potassium ion charge

Potassium is in group 1 of the periodic table. It loses 1 electron to form an ion, so the charge is +1.

Step2: Determine chloride ion charge

Chlorine is in group 17. It gains 1 electron to form an ion, so the charge is - 1.

Step3: Determine number of potassium ions in KCl

The chemical formula of potassium chloride is KCl. There is 1 potassium ion (K⁺) in one molecule of KCl.

Step4: Determine number of chlorine ions in KCl

In the formula KCl, there is 1 chloride ion (Cl⁻) in one molecule of KCl.

Answer:

What is the charge on the potassium ion? +1
What is the charge on the chloride ion? -1
How many potassium ions are in one molecule of potassium chloride? 1
How many chlorine ions are in a molecule of potassium chloride? 1
