Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an ...

Ancient rocks reveal a potassium-40 deficit, the first physical evidence of the proto-Earth and insights into early planetary ...

Scientists have created new extraheavy versions of three silvery metals in an advance that could lead to better understanding of how some elements are forged in stars. The new heavyweights are ...

The chemical properties of atoms depend on the number of protons in their nuclei, placing them into the periodic table. However, even chemically identical atoms can have different masses – these ...

Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...
