Helium.<\/p>\n<p>An alpha particle is a positively charged particle that is emitted from the nucleus of an atom during radioactive decay. It is composed of two protons and two neutrons, and has a mass of 4 atomic mass units (AMU). The nucleus of a helium atom is also composed of two protons and two neutrons, so an alpha particle is essentially the same as a helium nucleus.<\/p>\n<p>The other options are incorrect because they are not composed of two protons and two neutrons.
