Which element has the symbol B?

Which element has the symbol B?

• A. Boron
• B. Neon
• C. Sodium
• D. Magnesium

Answer: (A)

Chemical symbols are the official shorthand for elements, usually one or two letters taken from the element’s name. The symbol B is the one-letter symbol assigned to boron, so the element with symbol B is boron (atomic number 5). Neon, sodium, and magnesium have symbols Ne, Na, and Mg respectively, so they are different elements.
