What Is the Element “Nu”?
No element has the chemical symbol “Nu.” Other symbols that may be mistaken for “Nu” include: “Na,” “Ne,” and “N.” “Na” stands for sodium, while “Ne” stands for neon, and “N” stands for nitrogen. Another possible element that could be misread as “Nu” is “Au,” which stands for gold.
Sodium is an alkali metal with the atomic number 11, while nitrogen is a non-metal with the atomic number seven. Neon is an inert gas, and its atomic number is 10. Gold is a transition metal; its number is 79, so it is the heaviest of the elements listed here. The atomic number represents the number of protons in the nucleus of an atom, so a sodium atom, for example, has 11 protons.
