It happens all over the periodic table. The chemical symbol for lead is Pb. For mercury, Hg. For antimony, Sb. My chemistry teacher in high school cracked up every time she referred to the symbol ...

Aside from presenting the chemical symbols and atomic numbers for each element, the new tabulation also shows what a particular element is commonly used for. Interactive Periodic Table Helium (He ...

But arguably the most boring aspect was memorizing the periodic table–and all its damn elements, symbols, and atomic numbers. Now one Los Angeles company plans to spice up the periodic table ...

Elements with atomic numbers 113, 115, 117, and 118, have been added to the periodic table, according to the International Union of Pure and Applied Chemistry (IUPAC).

The table starts with the simplest atom, hydrogen, and then organizes the rest of the elements by atomic number, which is the number of protons each contains.

A new version of the periodic table arranges elements by protons instead of electrons. Because the old one was getting pretty stale.

The giant chart, which stood eight stories tall and some 200 feet wide, consisted of 111 posters, each displaying the symbol and atomic number of a chemical element.

The Periodic Table is an amazing chemistry tool that is organized with elements in order of increasing atomic number. The properties of the element change as you move across the row, but are similar ...

Changes to the periodic table, including new elements and updated atomic weights, highlight its dynamic nature and the evolution of chemical science.

With the discoveries now confirmed, "The 7th period of the periodic table of elements is complete," according to the International Union of Pure and Applied Chemistry.

Most elements on the periodic table have at least one stable form. But some don’t. Here’s how long those unstable members endure.
