Problem
A materials scientist is selecting elements to form oxide coatings with specific acid–base character. The table below gives first-ionization energy (IE) and electronegativity (EN) data for four candidate elements.| Element | IE / | EN (Pauling) |
|---|---|---|
| W | 496 | 0.93 |
| X | 738 | 1.31 |
| Y | 1451 | 2.96 |
| Z | 1000 | 2.16 |
