There are 118 elements on the periodic table as of 2026.

Quick Scoop: Why 118?

  • The elements are numbered by their protons (atomic number) from 1 (hydrogen) up to 118 (oganesson).
  • Elements 113, 115, 117, and 118 were the most recent additions, officially named in 2016, bringing the total to 118.
  • Of these 118, about 90‑plus occur naturally, while the rest are man‑made in laboratories and often very short‑lived.

So if you see a modern periodic table today, you should expect it to go from H (1) through Og (118).
