How does IUPAC decide if a discovery is real?

In one line

The rule

IUPAC (International Union of Pure and Applied Chemistry) uses a set of guidelines to decide if a new scientific discovery, like a new element, is genuine. The evidence must be repeatable, clear, and agreed upon by experts.

Let's understand it simply

Imagine you and your friends are playing cricket. Someone claims they hit a six, but nobody saw it. Would you just believe them? No. You would want proof: maybe a video, or many people saw it, or the ball is found outside the boundary. IUPAC does the same for science. When a scientist says, “I found a new element,” IUPAC asks for proof. They check if the experiment was done correctly, if others can repeat it, and if the results are clear. Only then do they accept the discovery.

How it works

1. Submission of Evidence: Scientists send all their data and results to IUPAC.
2. Peer Review: Other experts (not involved in the discovery) check the evidence to see if it is strong and clear.
3. Reproducibility: The experiment must be repeatable by other scientists in different labs.
4. Clear Identification: The discovery must have unique features (like a new element’s atomic number) that prove it is new.
5. Joint Working Group Decision: A special team from IUPAC and IUPAP (for physics) reviews everything and makes the final decision.
6. Official Announcement: If all steps are passed, IUPAC announces the discovery and gives it a name.

The story behind it

IUPAC was formed in 1919 to bring order to chemical names and discoveries. In the 20th century, many scientists claimed to find new elements, but some were mistakes or even fakes. To avoid confusion, IUPAC created strict rules. In the 1990s and 2000s, there were big arguments about who discovered elements like 112 (copernicium). IUPAC’s careful process helped settle these fights. One memorable detail: sometimes, two teams in different countries claim the same discovery, so IUPAC has to decide who gets the credit.

Where you see it in real life

• New Elements: When scientists claim to find a new element (like element 118, oganesson), IUPAC checks the proof before it is added to the periodic table.
• Naming Elements: IUPAC decides the official name and symbol for new elements after confirming the discovery.
• Chemical Compounds: If a new compound is discovered, IUPAC checks if it is really new and not already known by another name.
• Scientific Journals: Research papers about new discoveries are checked using IUPAC rules before being published.
• School Textbooks: The periodic table you see in your book only includes elements approved by IUPAC.
• Disputes: When two labs argue over a discovery, IUPAC’s decision is final.

Why it matters

• Trust in Science: Ensures only real, proven discoveries are accepted, so scientists and students can trust the information.
• Global Agreement: Scientists everywhere use the same rules, so there is no confusion.
• Prevents Cheating: Stops false claims and mistakes from entering textbooks and research.
• Foundation for Future Research: New discoveries build on old ones, so it is important to be sure they are real.

Common mistakes

• Thinking any claim is accepted: IUPAC does not accept discoveries just because someone says so; strong proof is needed.
• Ignoring reproducibility: If others cannot repeat the experiment, IUPAC will not accept it.
• Confusing discovery with naming: Discovery must be proven first; naming comes later.
• Believing it is a quick process: It can take years for IUPAC to check and confirm a discovery.

Remember it

IUPAC only accepts a discovery if the proof is strong, repeatable, and agreed by experts.
