Boron Atom Structure - Protons, Neutrons, and Electrons Explained #275709 (License: Personal Use)

This educational diagram illustrates the atomic structure of boron (atomic number 5), with a nucleus containing 5 protons and 6 neutrons, surrounded by 3 electrons distributed across two energy levels-2 in the first shell and 1 in the second. The blue cloud represents the electron probability region or valence shell boundary. It serves as a clear visual aid for introductory chemistry concepts.

Used in educational websites, science textbooks, and classroom presentations to teach atomic theory, periodic table fundamentals, and electron shell models; matches user intent for learning basic atomic structure.
