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

KCl

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.

b barium and chlorine

Explanation:

chemical bond formed between 2 oppositely charged ions

its going to be mutualism cuz they both benefit from the relationship.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
