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.

Scientists discovered a method to create element 116 using a titanium beam, paving the way for future synthesis of element 120, the "holy grail" of chemistry.

1st Period: Hydrogen and helium—Electrons go into the first energy level. After the first level has two electrons, the next electron goes into the second level. 2nd Period: Lithium to neon—Electrons ...

Researchers have demonstrated a new way to make superheavy elements, offering a method to create element 120 — which would be the heaviest element ever made. Scientists at the Lawrence Berkeley ...

History of Periodic Table of Elements. Johann Dobereiner, a German chemist, was the first to consider trends among element properties in the early 1800s.

The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

Francium — the 87th element on the periodic table — is a naturally occurring, but incredibly rare, radioactive element. It forms and decays extremely quickly, so it has no practical uses, and ...
