Verified step by step guidance1
Recall that an atom consists of three main subatomic particles: protons, neutrons, and electrons.
Understand that the nucleus of an atom contains only protons and neutrons, which are tightly bound together.
Recognize that electrons orbit the nucleus in electron clouds or shells and are not found inside the nucleus.
Apply this knowledge specifically to beryllium, which, like all atoms, has protons and neutrons in its nucleus.
Therefore, the subatomic particles found in the nucleus of a beryllium atom are protons and neutrons.
