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 ...

A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged titanium atoms, or ions, into a californium target.

By the periodic table’s logic, all d-block elements should have filled s orbitals. But copper defies that logic. It should have the electron configuration [Ar] 3d 9 4s 2.

The periodic table shows all the atoms that everything in the known universe is made from. It’s kind of like the alphabet in which only 26 letters, in different combinations, make up many thousands of ...

But a better answer comes from the periodic table. There are a few elements—especially platinum and palladium—that have the amazing ability to absorb up to 900 times their own volume in ...

Palladium is a shiny metal used in manufacturing processes, ... The majority of the world's supply of this rare metal, which has the atomic number 46 on the periodic table of elements, ...

The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the ...

Meet nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og), the newest elements on the periodic table to receive names. But don’t get too attached to the nomenclature for these ...
