iodine and potassium form an ionic bond. iodine has seven electrons in its outer shell, and potassium has one electron in its outer shell. which conclusion is best supported by this information?\no iodine is a noble gas.\no potassium is a nonmetal.\no iodine becomes an ion with a negative 1 charge.\no potassium becomes an ion with a positive 7 charge.
Answer
Answer:
C. Iodine becomes an ion with a negative 1 charge.
Brief Explanation:
Iodine has 7 outer - shell electrons and gains 1 electron to achieve a stable octet, forming an anion with a - 1 charge. Potassium has 1 outer - shell electron and loses it to form a + 1 cation. Noble gases have full outer shells, and iodine is not a noble gas. Potassium is a metal. Potassium loses 1 electron to form a + 1 ion, not a + 7 ion.
