Answer:
C: Iodine becomes an ion with a negative 1 charge.
Step-by-step explanation:
An Ionic bond is a type of bond that is formed between a metal and a non-metal. It involves the transfer of electrons between atoms and occurs when a metal transfers valence electrons to non-metal. The result is that the metal loses electrons to form a positively charged ion (cations) and non-metals gain electrons to form negatively charged ions (anions).
In this case, potassium loses one electron forming a cation with a positive 1 charge. While Iodine which is a halogen gains an electron to form an anion with a negative 1 charge. Both atoms thus achieve the octet rule, where each atom has a maximum number of electrons in each energy level.
