Is sodium oxide a cation or anion?

Sodium oxide molecules are made up of two sodium cations and one oxygen anion. Thus, Na2O molecules feature two sodium-oxygen ionic bonds. The structure of sodium oxide molecules is illustrated below.

Can you make sodium oxide cation and anion?

Now, sodium is located in group 1 of the Periodic Table, which means that an atom of sodium has 1 valence electron. In order to complete its octet, sodium will lose this valence electron and form the sodium cation, Na+ . In order to complete its octet, oxygen takes in 2 electrons and forms the oxide anion, O2− .

Why is sodium sulfide yellow?

Commonly available grades have around 60\% Na2S by weight, which means that x is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as ‘sodium sulfide flakes’.
