The correct answer is: potassium and iodine.
To determine which two elements would bond together based on their ionic charges, we need to identify elements with opposite charges. In this case, elements from Group IA typically have a +1 charge, while elements from Group VIIA typically have a -1 charge.
Looking at the options provided, the element with a +1 charge is potassium (Group IA), and the element with -1 charge is iodine (Group VIIA). Therefore, the two elements that would bond together based on their ionic charges are potassium and iodine.
The correct answer is:
potassium and iodine.
