Did you know the center of mass can be outside the object itself? Learn what center of mass really means and see clear examples with everyday objects like bananas, donuts, and golf clubs.

The periodic table is arranged by atomic number, which is the number of protons in an element’s nucleus. The elements are arranged in order of increasing atomic number. The periodic table is also arranged by groups and periods. The...

The reactivity of an element is a function of how easily an element loses or gains electrons. To determine an element's reactivity, we can learn a lot from the periodic table, and its particular trends. The first element in the halogen...

Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the...

From Mendeleev’s original design to physicist-favorite “left-step” rendition, the periodic table of elements has gone through many iterations since it was first used to organize elements 150 years ago - each with its own useful insights...

There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life.

Hank reveals why our love affair with the rare earth elements has a dark side.

Not all of the naturally occurring elements were discovered here on Earth. Helium was discovered by examining sunlight, and that same technique is now teaching us about the composition of distant galaxies.
