its freshly exposed shiny surface rapidly turns dull as a thin layer of sodium oxide forms: Other metals may oxidise more slowly. Gold and other very unreactive metals do not oxidise in air at all.

The shiny grey magnesium strip changes to a white powder called magnesium oxide. Learn more about making a reactivity series in this guide. For example, sodium is burned to make sodium oxide.
“Our findings confirm that sodium ions require specific conditions ... found to induce degradation of the transparent conducting oxide (TCO) and contacts and result in fill factor losses.
