Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications.

Group Number: For main group elements (s- and p-block elements), the group number corresponds to the number of valence electrons. For example, carbon (C) is in Group 14, so it has 4 valence electrons.

Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons. The electrons are shaped into chiral coils of mass and charge ...

In this article, we will explore the definition and characteristics of valence electrons, learn how to determine them for various elements and discuss their significance in predicting chemical ...

Because of their unique chemistry, the rare earth elements can fine-tune light for many different purposes and generate powerful magnetic fields.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan.

Although atomic behaviours of these elements are often a key to resolve chemical or biological activities, they are hardly visible in transmission electron microscope because of their smaller ...

Scientists observed record-breaking electron mobility — seven times higher than in conventional semiconductors — with a material made from the same elements as quartz and gold.

Adding one more electron – to make lanthanum, the first in the series of rare earth elements – puts that electron in the fifth circle.

Electron diffraction is a high-resolution technique for studying the atomic structure of materials, offering advantages in nanoscale characterization, defect analysis, and in-situ studies compared to ...

Each tends to react with different elements. Electron-starved acids gravitate towards electron-rich areas on other atoms, while bases with “free” electrons attack atoms that are electron poor.
