• less than the energy that holds the atom together.

• 10 times as great as the energy that holds the atom together.

• as large as or larger than the amount of energy that holds the electron in its orbit.

• equal to or greater than 1.022 MeV, regardless of the energy that holds the electron in its orbit.
