An alpha particle is made up of two protons and two neutrons.
An alpha particle is made up of two protons and two neutrons.
The correct answer is: two protons and two neutrons.
To determine the composition of an alpha particle, you need to look at the atomic structure of an alpha particle. An alpha particle is actually a type of helium nucleus, consisting of two protons and two neutrons. Protons have a positive charge, while neutrons have no charge. The presence of both protons and neutrons in the nucleus helps to provide stability to the alpha particle. Therefore, the correct option is two protons and two neutrons.
