<h3>The correct options would be:</h3>
1, 3 and 4.
In an alpha decay, the atom's mass number is reduced by 4, and the atomic number is reduced by two following the emission of an alpha particle (2 protons and 2 neutrons).
In gamma decay, the atom releases energy spontaneously to stabilize itself, and this energy is released in the form of photons.
<h3>Hope this helps!</h3>
The answer is (D) microscopic. You can remember this, because the name is very close to "microscope," an instrument used to greatly magnify and observe tiny organisms and objects.
