Identify the correct combination of true (T) and false (F) for the following three statements.
STATEMENT-1: The -particle is the electron ejected from the orbits of an atom.
STATEMENT-2: In all radioactive transformations either an or a -particle (never both or more than one of each kind) is emitted by the atom.
STATEMENT-3: When a radioactive element decays through the emission of a -ray neither atomic number nor the mass number changes.
