Indium - Periodic Table and Atomic Properties

WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8. WebGallium-67 Tumor Imaging. Gallium-67 (Ga-67) was initially used as a bone-imaging agent and is still sometimes used for the assessment of infection. Ga-67 is sensitive for many cancers, including hepatocellular cancer, sarcomas, and lung cancer ( Table 12-12 ). For years, Ga-67 was primarily used in the assessment of lymphoma ( Fig. 12-19 ). novartis advisory board
