We aim to make complex subjects, like chemistry, approachable and enjoyable for everyone. Atoms tend to be most stable with a full outer shell (one which, after the first, contains 8 electrons), leading to what is commonly called the "octet rule". Atoms that do not have full outer shells will tend to gain or lose electrons, resulting in a full outer shell and, therefore, stability. Atypical Hemangioma Mimicking Metastasis on 18F-Sodium Fluoride Positron Emission Tomography-Computed Tomography and Magnetic Resonance Imaging: Gallium-68-Prostate-Specific Membrane Antigen Positron Emission Tomography Improves the Specificity of Bone Le.
