You probably remember that colorful, grid-like poster hanging on the wall of your high school chemistry class. The Periodic Table. It’s the map of everything. But if you actually look at the bottom rows, things start getting a bit weird. You see names like Oganesson and Tennessine—elements that sound like they belong in a sci-fi flick rather than a rock you’d find in your backyard.
So, let's get down to it. How many elements are there in nature?
If you want the short, textbook answer, it's 92. But honestly, science is rarely that clean. Depending on who you ask—a geologist, a nuclear physicist, or a guy with a metal detector—that number fluctuates. We usually say that everything from Hydrogen (number 1) to Uranium (number 92) occurs naturally. But then you’ve got these "ghost" elements like Technetium and Promethium that barely exist at all. It's a bit of a mess, really.
The Magic Number 92 (And Why It’s Complicated)
For decades, 92 was the golden number. Uranium sits at the end of the "natural" line because it’s the heaviest element found in any significant amount on Earth. It’s the "last" one. Or so we thought.
Here is the thing. Nature doesn't just stop because we drew a line on a chart.
Elements are defined by the number of protons in their nucleus. Hydrogen has one. Helium has two. Carbon has six. By the time you get to Uranium, you’re looking at 92 protons packed into a tiny space. It’s heavy. It’s unstable. It’s radioactive. Beyond Uranium, the nuclei become so massive and crowded that they basically fall apart almost instantly. These are the transuranium elements.
But wait.
Scientists eventually realized that Plutonium (94) and Neptunium (93) actually show up in nature too. You won't find a "Neptunium mine" anywhere, but if you look inside uranium ores like pitchblende, you’ll find trace amounts of these heavier elements created by natural neutron capture. So, if we’re being pedantic—and scientists love being pedantic—the number of natural elements is technically 94.
The Mystery of the Missing Elements
Now, let's talk about the holes in the map. Even though we say there are 92 or 94 elements "in nature," two of them are basically cosmic accidents.
- Technetium (43): This one is a total rebel. It’s light, sitting right in the middle of the table, but it has no stable isotopes. It decays so fast that any Technetium that was around when Earth formed is long gone. We only see it now because it’s produced in stars or created in labs for medical imaging.
- Promethium (61): Same deal. It’s rare. Like, "less than a pound of it in the entire Earth's crust" rare.
It’s kind of wild to think about. We have this massive planet, and yet for some elements, there is barely enough to fill a salt shaker scattered across the entire globe. If you're counting what you can actually go out and find, those two almost don't count. But they exist. Nature made them, even if it didn't make them to last.
The Superheavy Synthesis
Everything past Plutonium (94) is purely a product of human ingenuity. Elements 95 through 118 are synthetic. We make them in particle accelerators by smashing atoms together and hoping they stick. Most of them, like Oganesson (118), only exist for a fraction of a millisecond before they poof out of existence.

Does that mean they aren't "natural"?
Some physicists argue that these superheavy elements might exist in the chaotic aftermath of a supernova or a neutron star collision. If a star can crush atoms into a black hole, it can probably smash a few protons together to make Element 120, even if it only lasts for a heartbeat. But since we haven't caught them in the wild yet, they stay in the "man-made" column.
Why the Number Keeps Shifting
You might find older books that say 88. Or 90. Or 98. Why can't we agree?
It comes down to detection limits. As our technology gets better, we find "trace" amounts of things we thought were impossible. We’re basically detectives looking for fingerprints left behind by radioactive decay.
Take Astatine (85). It is often cited as the rarest naturally occurring element. At any given moment, there is probably less than an ounce of it on the entire planet. It’s constantly being created by the decay of heavier elements and then instantly decaying into something else. It’s a flickering candle. If you’re counting "how many elements are there in nature" based on what is permanently here, the number is much lower. If you’re counting anything that appears for even a second, the number climbs.
The Atomic Building Blocks of... Well, You
While there are 92-ish elements in the crust, nature is actually pretty picky about what it uses to build life. You are mostly made of just six: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur.

It’s a bit humbling. There’s a whole universe of exotic metals, radioactive gases, and strange earth elements out there, but life basically looked at the periodic table and said, "I'll just take the top row, thanks."
But don't ignore the weird ones. You need Iodine for your thyroid. You need Cobalt for Vitamin B12. You even have a tiny bit of Copper and Zinc in you. Nature uses the rare stuff as the "spices" in the recipe of life.
Spotting Elements in the Wild
If you want to see these elements for yourself, you don't need a lab. You just need to know where to look.
- Helium: Check a birthday balloon. It’s the second most abundant element in the universe, but it’s so light that Earth’s gravity can’t hold onto it. Every time a balloon pops, that helium eventually floats out into space and is gone forever.
- Silicon: Look at a beach. Sand is basically silicon and oxygen. It’s the backbone of all our tech.
- Argon: You’re breathing it right now. It makes up about 1% of our atmosphere. It’s lazy, it doesn't react with anything, and it’s just... there.
- Lithium: It’s in your phone battery, but it’s also found in brine pools in South America.
Actionable Takeaways for the Curious Mind
Knowing how many elements are there in nature isn't just for winning trivia night. It changes how you see the world.
If you want to dive deeper into the elemental makeup of the world around you, here is how to start:
- Download a dynamic periodic table app: Standard paper tables are boring. Use an app like Ptable or the Royal Society of Chemistry’s version. They show you exactly which elements are solids, liquids, or gases at different temperatures.
- Check your labels: Look at your multivitamin or the back of your shampoo bottle. You'll see Manganese, Selenium, and Magnesium. These aren't just chemicals; they are raw pieces of the Earth's crust that your body has learned to use.
- Explore Geology: If you really want to see elements 1 through 92 in their natural habitat, start a rock collection. A piece of Granite is a chaotic cocktail of Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, and Potassium.
- Follow the "Island of Stability" research: Nuclear physicists are currently trying to reach a point where superheavy elements might actually become stable again. It's one of the most exciting frontiers in science. If they find it, the number of "elements" we interact with could change forever.
The universe is built from a very specific set of Lego bricks. We’ve found 92 of them hiding in the dirt and the air, and we’ve cooked up a few dozen more in our labs. Whether the "real" number is 92, 94, or 118, the reality is that everything you’ve ever touched, loved, or eaten comes from this one short list. That's pretty incredible when you think about it.
