What are 3 facts about the periodic table?
Fun facts about the Periodic Table
- Carbon is unique in that it is known to form up to 10 million different compounds.
- Francium is the rarest element on earth.
- The only letter not in the periodic table is the letter J.
- The country Argentina is named after the element silver (symbol Ag) which is argentum in Latin.
What was unusual about Mendeleev’s periodic table?
Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and physical properties of the elements next to a gap, he could also predict the properties of these undiscovered elements. The element germanium was discovered later.
What are 5 facts about the periodic table?
15 Fun and Surprising Facts About the Periodic Table of Elements
- Dmitri Mendeleyev is the inventor of the modern periodic table.
- Scientists used battery polarity to weigh the elements.
- The periodic table reflects its creator’s love for card games.
- It was used to correctly predict elements that hadn’t been discovered.
What was amazing about Mendeleev’s first periodic table?
Mendeleev’s formulation was clearly superior in several respects to the work of contemporary classifiers: it was the clearest, most consistent, and most systematic formulation, and Mendeleev made several testable predictions based on it. It was not, however, free from error.
Why is the periodic table interesting?
In fact, the periodic table is so accurate that it allows scientists to predict the chemical and physical properties of elements that hadn’t yet been discovered. “The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties,” said Mendeleev.
What is the rarest element in the periodic table?
element astatine
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What was Mendeleev’s genius?
Unlike those other scientists, Mendeleev predicted that there would be more chemical elements to come. And he was right! Today, the periodic table has 118 elements. But in Mendeleev’s time, scientists only knew of 63 elements.
Why did scientists not accept Mendeleev’s table?
Because the properties repeated themselves regularly, or periodically, on his chart, the system became known as the periodic table. In devising his table, Mendeleev did not conform completely to the order of atomic mass. He swapped some elements around.
Did Mendeleev earn a Nobel Prize?
While Mendeleev was never awarded the Nobel Prize (he was nominated in 1905, 1906 and 1907) his work paved the way for many other laureates who went onto be recognised for their elemental discoveries.
How did Mendeleev change the world?
On 17 February 1869, Russian chemist Dmitri Mendeleev jotted down the symbols for the chemical elements, putting them in order according to their atomic weights and inventing the periodic table. It was perhaps the greatest breakthrough in the history of chemistry.
How was Mendeleev’s periodic table arranged?
Mendeleev published his table, which he called a “periodic system,” in 1869. Mendeleev arranged the elements in order of increasing weight and broke them into rows such that elements in each column shared valence, the number of other atoms they combined with, as well as other properties.

Fun Facts about Elements
- Elements found on Earth and Mars are exactly the same.
- Hydrogen is the most common element found in the universe.
- Isotopes are atoms of the same element, with different numbers of neutrons.
- In ancient times the elements referred to fire, earth, water, and air.
