The Periodic Table of the Elements is a structured masterwork organizing all 118 discovered elements by their atomic number and chemical properties. Originally devised by Dmitri Mendeleev in 1869, it serves as the ultimate cheat sheet for understanding the building blocks of our universe. Licensed by Google Fast Facts 118 total elements currently populate the modern table. 94 elements occur naturally on Earth. 24 elements are strictly synthetic and created in labs.
4 states of matter (solid, liquid, gas, and unknown) are represented.
Only 2 elements are liquid at room temperature: Mercury and Bromine.
Hydrogen is the lightest and most abundant element in the universe.
Oganesson is the heaviest element on the table with an atomic number of 118.
The letter ‘J’ is the only letter of the alphabet not used as an element symbol. Hidden Secrets & Quirks
Mendeleev’s time travel: Mendeleev left intentional blank spaces in his original grid. He correctly predicted the existence and exact properties of undiscovered elements like Gallium and Germanium years before they were found.
The vanishing spoon: Gallium melts at just 29.76°C (85.57°F). A famous science prank involves giving someone a spoon made of Gallium, which instantly melts into liquid metal when stirred into a warm cup of tea.
Stardust origin: Every bit of Calcium in your bones and Iron in your blood was forged inside the hearts of dying stars and ancient supernova explosions.
Technetium anomaly: This is the very first artificially made element. Despite having a low atomic number (43), it is highly unstable and radioactive, existing naturally on Earth only in trace amounts.
Country connections: Many elements are named after places. Francium (France), Polonium (Poland), Germanium (Germany), and Americium (America) were named to honor the homelands of their discoverers.
The Ytterby goldmine: A single quarry in the small Swedish village of Ytterby is responsible for the discovery of four different elements: Yttrium, Terbium, Erbium, and Ytterbium.
