Periodic Element Generator

Generates a random chemical element from the periodic table, with its symbol and atomic number — useful for chemistry practice or a quick classroom prompt.

What this generator does

Picks an element at random from the periodic table, for a research task or a quiz. Every element is equally likely, which is what makes it fair — a weighted list would keep returning the famous ones.

What you'll get

This generator draws from a hand-checked list of 18 entries. Here is a spread of 6 of them, so you can see the style before you generate:

  • Hydrogen (H, atomic number 1)
  • Nitrogen (N, atomic number 7)
  • Sodium (Na, atomic number 11)
  • Sulfur (S, atomic number 16)
  • Zinc (Zn, atomic number 30)
  • Mercury (Hg, atomic number 80)

A fixed sample of the list, not a live draw — your own results are picked at random from all 18, without repeating until the list runs out. IUPAC periodic table of the elements (element names, symbols and atomic numbers are standard scientific nomenclature). Last reviewed 2026-08-03.

How to use this tool

  1. Press generate for an element.
  2. Use it for practice, or generate again for a different one.

Common use cases

  • Chemistry classroom practice
  • Quiz or flashcard prompts
  • General science trivia

Practical tips

  • For a class research task, generate one per pupil in advance so the well-known elements do not all go first.
  • Ask for the group and period as well as the name; that is where the periodic table's structure actually lives.

Entries are chosen with your browser's cryptographic random number generator, so every entry on the list is equally likely. How Generate Random works.
