Question

Quizplus · Accepted Answer

The missing particle in the given code is an alpha particle, which is a type of particle that consists of two protons and two neutrons bound together, identical to the nucleus of a helium atom. This is indicated by the code's format, which resembles the naming convention used for alpha particles in nuclear physics, such as 4He2 or 4α. The other options, positron, beta particle, and gamma particle, do not fit the pattern of the code and are not consistent with the characteristics of an alpha particle.
