A) less than the energy that holds the atom together.
B) 10 times as great as the energy that holds the atom together.
C) as large as or larger than the amount of energy that holds the electron in its orbit.
D) equal to or greater than 1.022 MeV,regardless of the energy that holds the electron in its orbit.
