Can you name everything from Ac to Zr? Test your knowledge of the periodic table and see if you can top the leaderboard ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to ...

All matter–oceans, land, atmosphere, humans, animals, plants, food, materials, products, buildings–is made from 118 known chemical elements. These elements are ordered in the periodic table of ...

Since Mendeleev's time, scientists have discovered new elements, expanding the periodic table. The most recent additions include nihonium, moscovium, tennessine, and oganesson, which were officially ...

The periodic table currently has 118 chemical elements (SN: 11/30/16).The five heaviest elements were all produced using a beam of calcium-48. That’s a variety, or isotope, of calcium with 28 ...

The periodic table, first invented by Dmitri Mendeleev in 1869, groups the 118 known chemical elements according to their chemical properties. Because elements in the same parts of the periodic ...

Instead, they may be made of naturally occurring "superheavy elements" beyond those listed in the periodic table — our current best catalog of 118 chemical elements — new research suggests.

“The periodic table is supposed to tell you what the chemical trends are,” LBNL’s Pore says. For heavier elements, in which relativistic effects start to rule, that’s not necessarily true.

In this periodic table of elements quiz, you have 10 minutes to name as many elements as you can, given only their symbol, atomic weight and the broad group they live in.
