Fe+2 will form the most ionic bonds with:
Correct answer: B. S-2
- A. N-3
- B. S-2
- C. P-3
- D. F-1
Explanation
Fe is the symbol for iron (a transition metal), and S is the symbol for sulfur (a nonmetal). When the iron atoms bond with the sulfur atoms, they create a sulfide anion with a charge of 2-, and an iron cation, with a charge of 2+, hence the (II). This compound is used in the stainless steel and iron industries. Fe + S → FeS (heat)

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
