The table shows the electronegativity values of four unknown elements on the Pauling scale. Electronegativity Values
Unknown Element Electronegativity
W
1.5
x
0.93
Y
2.0
Z
3.2
Which two elements are most likely to form an ionic bond together?

X and Z

Explanation:

If the difference in electronegativity between two atoms is greater than 1.7, they will form an ionic bond.

W and Z: 3.2 - 1.5 = 1.7  no

X and Z: 3.2 - 0.93 = 2.27 yes

Y and Z: 3.2 - 2.0 = 1.2  no

W and Y: 2.0 - 1.5 = 0.5  no

X and Y: 2.0 - 0.93 = 1.07  no

W and X: 1.5 - 0.93 = 0.57  no

X and Z are most likely to form an ionic bond together.

Hope this helps.
