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?\niodine is a noble gas.\npotassium is a nonmetal.\niodine becomes an ion with a negative 1 charge.\npotassium becomes an ion with a positive 7 charge.

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?\niodine is a noble gas.\npotassium is a nonmetal.\niodine becomes an ion with a negative 1 charge.\npotassium becomes an ion with a positive 7 charge.

Answer

Explanation:

Step1: Recall noble - gas property

Noble gases have a full outer - shell of electrons. Iodine has 7 outer - shell electrons, so it's not a noble gas.

Step2: Recall metal/non - metal property

Potassium is an alkali metal, not a nonmetal.

Step3: Analyze iodine's ion formation

Iodine has 7 outer - shell electrons. It gains 1 electron to achieve a stable octet, forming an ion with a - 1 charge.

Step4: Analyze potassium's ion formation

Potassium has 1 outer - shell electron. It loses this 1 electron to achieve a stable electron configuration, forming an ion with a + 1 charge, not + 7.

Answer:

Iodine becomes an ion with a negative 1 charge.
