To create their coordination complex with promethium (see 2D structure at right), researchers first harvested promethium-147 (shown in vial at left as a nitrate salt) from nuclear waste. Credit: D ...

Humans are made of many chemical elements that work together to create our complex bodies. The elements are like pieces of a puzzle, each playing a unique and essential role in maintaining our health.

One of the rarest and most mysterious elements in the periodic table has finally given up some crucial chemical secrets, eight decades after its discovery. Researchers at Oak Ridge National ...

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 4D Periodic Table of Chemical Elements is an answer to this question, having a geometric structure related to the hypercube, a four-dimensional cube. Professor Haresh Lalvani published his paper ...

Elemental music: Interactive periodic table turns He, Fe, Ca into Do, Re, Mi. Hydrogen has a scale pattern; zinc "sounds like an angelic vocalist singing with vibrato." ...

Give each student a Periodic Table of Energy Levels activity sheet. This table contains energy level models for the first 20 elements. The electrons are included only for the atoms at the beginning ...

Scientists are using AI to build a “periodic table of shapes” filled with Fano varieties—the basic “atomic structure” of geometry.

T he periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

Designing to Embrace a Wider Periodic Table Today, the supply chain uses a much wider array of elements from the periodic table than in the past decade. As a result, sourcing is more complex.
