Which of the following compounds is formed when sodium reacts with chlorine? (2021)

Which of the following compounds is formed when sodium reacts with chlorine? (2021)

Step 1: Understand that sodium (Na) is a metal and chlorine (Cl) is a non-metal.
Step 2: Know that when a metal reacts with a non-metal, they often form an ionic compound.
Step 3: Recognize that sodium has one electron in its outer shell and wants to lose it to become stable.
Step 4: Understand that chlorine has seven electrons in its outer shell and wants to gain one electron to become stable.
Step 5: When sodium loses its electron, it becomes a positively charged ion (Na+).
Step 6: When chlorine gains that electron, it becomes a negatively charged ion (Cl-).
Step 7: The positive sodium ion (Na+) and the negative chloride ion (Cl-) attract each other.
Step 8: This attraction forms sodium chloride (NaCl), which is table salt.
