Question

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?

Answer 1

X and Z

Step-by-step explanation:

ionic bonds form between elements with great differences between their respective electronegativity. X and Z have the greatest difference out of any other pair option given, thus they are most likely to bond ionically!

:) hope i help anyone

Answer 2

X and Z

Step-by-step 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.
