List of Monatomic Elements
The noble gases exist as monatomic elements:
helium (He)
neon (Ne)
argon (Ar)
krypton (Kr)
xenon (Xe)
radon (Rn)
oganesson (Og)
The atomic number of a monatomic element is equal to the number of protons in the element. These elements may exist in various isotopes (varying number of neutrons), but the number of electrons matches the number of protons.
