Question

examine the lewis dot structure for potassium iodide. why are there 6 dots around the symbol for iodine (i)? select two correct answers.

Explanation:

• In a Lewis dot structure, the dots represent valence electrons. For iodine in potassium iodide (KI), it gains an electron to achieve a full outer shell. The octet rule states that atoms tend to gain, lose, or share electrons to have 8 electrons in their outer shell (for most atoms). So, the 8 dots around iodine represent its valence electrons that add up to 8 (after gaining one electron from potassium).

Answer:

• Second option: Eight electrons is the maximum to fill the outer shell for this compound.
• Fifth option: The valence electrons from potassium combine with those for iodine, adding up to 8.
