Question

why does the emission of an alpha particle always result in transmutation? (1 point) the atom is converted to helium. the number of protons in the atom changes. energy is released from the nucleus of the atom. the protons in the large atom change to neutrons

Explanation:

An alpha - particle is a helium - 4 nucleus, consisting of 2 protons and 2 neutrons. When an atom emits an alpha - particle, its atomic number (number of protons) decreases by 2 and its mass number decreases by 4. This changes the identity of the atom, which is transmutation.

Answer:

The atom is converted to helium.
