An alternative periodic table of elements focusing on highly charged ions reveals new science that could support the quest for more accurate optical atomic clocks ...

The periodic table is in the opposite corner above a bench with a microscope (second image). Once you have both, you can start to piece together the answer.

Only a Few Grams of This Element Exist—and Scientists Have Used It to Break the Rules of the Periodic Table Doesn’t “organometallic sandwich” sound appetizing?

Ecological impacts of single-axis photovoltaic solar energy with periodic mowing on microclimate and vegetation Yudi Li 1,2 * † Alona Armstrong 3,4 † Christopher Simmons 5 † Noah Z. Krasner 1,2 † ...

Ionization energy tends to decrease as you move down a group in the periodic table. This is because, with each successive element, an additional electron shell is added, increasing the distance ...

Show students that you have 80 cards (4 for each of the first 20 elements). Before distributing the cards, explain that each card contains information about electrons and energy levels for the first ...

Have students look at their Periodic table of energy levels for elements 1–20 distributed in lesson 3. Explain that the two electrons in the hydrogen molecule (H 2) can be thought of as “belonging” to ...
