Question

Which pair of elements forms the most ionic bond? Refer to the periodic table.

A) K and CI
B) Be and CI
C) Li and CI
D) O and CI ​

Answer 1

b barium and chlorine

Step-by-step explanation:

chemical bond formed between 2 oppositely charged ions

Answer 2

KCl

Step-by-step explanation:

Look at the electronegativity differences between the pairs of elements:

KCl: 3.16 - 0.82 = 2.34

BeCl: 3.16 - 1.57 = 1.59

LiCl: 3.16 - 0.98 = 2.18

ClO: 3.44 - 3.16 = 0.28

KCl has the highest electronegativity difference; thus it is the most ionic bond of the 4.
