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 bottom ...

The periodic table is used in chemistry to organize different elements. Elements are atoms with a different number of protons and electrons. Protons are particles that are in center of the atom and ...

Your support goes further this holiday season. When you buy an annual membership or give a one-time contribution, we’ll give a membership to someone who can’t afford access. It’s a simple way for you ...

The periodic table contains a wide array of elements, numbered from one (hydrogen) to 118 (oganesson), with each number representing the number of protons stored within an atom's nucleus. Scientists ...

A staple in every science classroom is the periodic table of elements, and for many it is their first introduction to the vast mysteries of the natural world. Now physicists from Kyoto University have ...

The periodic table may soon gain a new element, physicists at Lund University in Sweden announced Tuesday. A team of Lund researchers is the second to successfully create atoms of element 115.

Scientists in Japan think they've finally created the elusive element 113, one of the missing items on the periodic table of elements. Element 113 is an atom with 113 protons in its nucleus — a type ...

Physicists develop a 'nuclear periodic table'. While the traditional table is based on the behavior of electrons in an atom, this new table is based on the protons in the nucleus. Protons have ...

For now, they’re known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...
