Abstract: Atoms are lonely hearts that are constantly in search of partners to bring stability to their lives—at Least that's the premise of our Atomic Dating Game, a chemistry activity that helps students visualize and understand how and why atoms combine.
With the exception of the Noble Gases, atoms are unstable on their own.
The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.
If the game is successful, students will discover logical pairings of whole families on the periodic table.
When students finish playing, they understand the logic inherent in the shape of the periodic table.
This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit.
Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such.
