Another weekend has arrived, and that means new hints are popping up in Cookie Jam. If you’re stuck on “Au on the periodic ...

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.

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning.

Give each student a copy of the periodic table of the elements, the periodic table of elements 1–20, and the activity sheet. Students will use the periodic table of elements 1–20, along with the ...

We explore if it's really possible that new elements exist beyond the periodic table. Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We ...

Phelps contributed to the discovery that filled in square 117 on the periodic table, creating tennesine (Ts), the second-heaviest known element on Earth.

A t the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact ...

The scientist already had broken barriers when she joined an international mission to do something else unprecedented: Create Element 117.

Studying the Periodic Table of Elements and the nuclear landscape in the superheavy region will generate new ideas and methods that will impact nuclear and atomic physics, astrophysics, and chemistry.
