A calcium atom can have its highest energy level be filled by forming an ionic bond with a single iodine atom. True or false?

OpenStudy (jfraser):

False. Calcium needs to lose 2 electrons to empty its highest energy level, and a single iodine atom can only accommodate 1 additional electron. You'd need a second iodine atom to fully empty the calcium's highest occupied level.
