Analyze: Electrons are arranged in orbits called energy levels. The Gizmo shows all of the first two energy levels but only part of the third energy level. How many electrons can fit in the first energy level

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
