Question

based on its electron configuration, which element will most likely gain electrons from another element when forming an ionic compound?
potassium (k)
vanadium (v)
iodine (i)
xenon (xe)

Explanation:

Non - metals tend to gain electrons in ionic compound formation. Potassium is a metal, vanadium is a transition metal. Iodine is a non - metal in Group 17, and has 7 valence electrons, so it wants to gain 1 electron to achieve a stable octet. Xenon is a noble gas with a stable electron configuration and is not likely to gain electrons.

Answer:

C. Iodine (I)
