Trends on the Periodic Table: Students learn to describe the pattern in atomic number, atomic mass, atomic radius, ionization energy, and electron affinity as they look across a period and down a ...

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 ...

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

Using lasers beams to measure the nuclear radius of isotopes at the end of periodic table Elements at the end of the periodic table are produced artificially via accelerator-driven nuclear ...

APPLICATION to NEXT GENERATION SCIENCE STANDARDS HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy ...

Chemistry Three reasons why the periodic table needs a redesign Chemists can't agree on the best way to arrange the elements, prompting proposals of everything from spiral-shaped alternatives to ...

In their new version of the periodic table, Allahyari and Oganov arranged the elements only based on their radius and electronegativity properties.

Everything Worth Knowing About The Periodic Table Learn all about the 118 combinations of protons, neutrons and electrons that make up our world.

Russian scientists designed a periodic chart where elements are grouped by atomic radius and electronegativity. Elements that form simple compounds would be grouped together.

If you are intimidated by the periodic table, then this introduction through the first column of elements will give you a feel for how and why the elements are arranged in this order.
