240,000 mi

240,000 mi. It takes light just over one second to travel from the moon to the earth. Its nucleus is a single proton. And one distant electron moves around it. The simplest atom is hydrogen.

Radiation PowerPoint

Radiation PowerPoint. By: Joy Mihanni And Jonathan Samuels . Outline. Alpha Emission. The reason alpha decay occurs is because the nucleus has too many protons which causes an excessive repulsion. A radioactive nucleus that undergoes alpha emission emits a helium nucleus, 4 2 He.
