Question

Which pair of elements listed below will undergo ionic bond formation? a) Na and K, b) C and Cl, c) C and H, d) Na and Cl​

Answer 1

Answer:

Ionic compounds are formed by electrostatic attraction between a cation(metal ion) and anion (non-metal ion) of similar size. If the size difference is such that cation is small and anion is very large, they form bond with more covalent character.

Answer 2

Pair of elements that will undergo ionic bond formation is d) Na and Cl

• Ionic bonds are only formed between two oppositely charges ions. Moreover, if the electronegativity difference is large then a particular bond has more ionic character.
• Hence, among the given pairs of elements, Na and Cl have opposite charges and greater electronegativity differences. So, this pair will form an ionic bond.
• During NaCl bond formation, Na loses one electron to form cation Na+ while Cl gains one electron to form anion Cl-.
