What element has the symbol 'No'?

The story behind the answer

Nobelium is the correct answer because its chemical symbol is No. The others have different symbols: Nickel is Ni, Neodymium is Nd, and Nitrogen is N. Nobelium (atomic number 102) is a synthetic, highly radioactive actinide element, named in honor of Alfred Nobel, the inventor of dynamite and founder of the Nobel Prizes.

Memory tip: Think “Nobel Prize says ‘No’”—No stands for Nobelium. Its name also fits the actinide trend of honoring scientists (like Curium and Einsteinium). Discovered through particle accelerator experiments and existing only in tiny, short-lived amounts, Nobelium highlights how new elements are often created, not found in nature.
