Beryllium Atomic Structure Concepts

The video tutorial explains how to determine the number of protons and electrons in a beryllium ion (Be2+). It starts by discussing neutral beryllium, where the atomic number equals the number of protons and electrons. The tutorial then explains that ions differ in the number of electrons, not protons. A visualization is used to show electron shells and energy levels, illustrating how Be2+ loses two electrons to become a positive ion. The video concludes with a reference to finding neutrons.
