What is the chemical symbol for Sodium?

Na So S Nd

Correct Answer:

Explanation:

Symbols on the periodic table are short abbreviations for elements, often using letters from the element’s name or its Latin name. For sodium, the symbol is Na, with an uppercase N and a lowercase a. This comes from natrium, the Latin name for sodium, which is why the symbol isn’t a direct match to the English word “sodium.” You’ll also see S representing sulfur, Nd representing neodymium, and “So” isn’t used because no element has that symbol. So, Na is the correct symbol because it follows the standard convention and reflects the Latin origin of the element’s name.
