Radioactive decay occurs when an atom has either to many or to few neutrons and becomes unstable and start to emit radio active radioactive radiation and the atom start to decompose.
At the end two things can happen either the atom will transform in a new element with a lower atomic # and atomic mass # or the remaining neutron will transform into an electron and be on its own way

The correct answer is gravity.
The planets and other heavenly bodies are attracted towards the earth by the earth's gravity. The pull which is formed by the gravity of earth holds the objects near the earth surfaces. The planets and atmosphere is also kept around the earth's surface by the gravity.
