Periods and families in the periodic table are described. Organization of the Periodic Table: Periods and families in the periodic table are described. Students learn to determine the number of energy ...

Chemistry has broken the spirits of many struggling high-schoolers and university students alike, but there might be a handy tool that can finally guide you through the various elements and help you ...

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 ...

Recognize these rows and columns? You may remember a detail or two about this mighty table’s organization from a long-ago chemistry class. Elements are ordered according to their number of protons, or ...

Students learn to describe the pattern in atomic number, atomic mass and atomic radius. Trends on the Periodic Table: Students learn to describe the pattern in atomic number, atomic mass, atomic ...

The periodic table is part of the bedrock of chemistry education. Students use it to look up values like an element’s atomic mass, and it serves as a visual reference for the trends in physical ...

Scientists have captured the fundamental chemistry of the element berkelium, or Bk on the periodic table. A little known -- and difficult to obtain -- element on the fringes of the periodic table is ...

Researchers have directly observed the heaviest atom yet participating in a chemical reaction and forming a molecule. The finding pushes “superheavy” chemistry, which involves extremely massive ...

The Chemistry Graduate Student Association and the American Chemical Society Drexel Student Affiliates had a very important prayer for the afternoon of Oct. 24: A relatively clear day with little to ...

Researchers used a particle accelerator and co-precipitation to study the chemical reactivity of single rutherfordium atoms. Such experiments will continue the advancement of relativistic chemistry ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...
