Choose the pair of elements that will most likely have the greatest ionic character. a. K and N
b. K and S
c. N and Br
d. S and Br

K and N

Explanation:

Ionic character depends on the electronegativity difference between the bonding elements. The greatest the elctronegativity diffference the greatest the ionic character. The electronegativity difference between K and N is the greatest among the four options as N is one of the most electronegative elements.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.
