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 ...

In a random moment, all energy is lost. The unstable subject cannot help but decay, slowly but surely, letting go of particles to become stable. It loses itself to become balanced again. This is a ...

A new tool at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) will be taking on some of the periodic table's latest heavyweight champions to see how their masses ...

Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

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 amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the ...
