Which two elements in the list would bond together based on their ionic charges?
A. calcium and potassium
B. potassium and neon
C. potassium and iodine
D. calcium and neon
Answer:
It's C. Potassium and iodine
The two elements in the list that would bond together on their ionic charges is potassium and iodine. The correct option is C.
What is ionic bond?Ionic bond, also known as electrovalent bond, is a type of linkage formed in a chemical substance by the electrostatic attraction of ions with opposite charges.
When the valence (topmost layer) electrons of one atom are indefinitely transmitted to another, a bond is formed.
The complete transmission of valence electron(s) among both atoms is referred to as ionic bonding.
It is a chemical bond that produces two opposing ions. The metal loses electrons in ionic bonds to become a positively charged cation, meanwhile the nonmetal chooses to accept those electrons to become a negatively charged anion.
Ionic bonds are formed by potassium iodide (KI). Iodine and potassium have very divergent electronegativities.
Since ionic bonds form between atoms with a large difference in electronegativity, the two atoms would form an ionic bond.
Thus, the correct option is C.
