No binary compound between beryllium and sodium.
Sodium combined with carbonate forms Na2CO3, which is called sodium carbonate.
The compound formed between sodium and selenium is named "sodium selenide" and has the formula Na2Se.
When two different elements combined chemically, a compound is formed. When two different elements are combined physically, a mixture is formed. In the case of barium and sodium, a mixture is formed because they are both metals and they do not combine chemically with each other. If you mix up the chemical symbols, it will be BANANA, but a banana is a fruit, not a chemical symbol of a compound. The actual answer is "a mixture of Barium and Sodium". That's all.
Sodium fluoride.
Sodium Fluoride is an Ionic Compound. It's Fluorine and Sodium with the formula NaF.
The compound formed when Na+ and Cl- are combined is called sodium chloride (NaCl).
