Web2 de set. de 2024 · Answer. The element symbol for oxygen is O and its atomic number is 8. The mass numbers for oxygen must be 8 + 8 = 16; 8 + 9 = 17; 8 + 10 = 18. The nuclear symbols are written this way (again, pretend the superscript and subscript are sitting right on top of each other beside the element symbol): 168 O, 178 O, 188 O. Or, you could write: Web9 de jun. de 2024 · Write the isotopic symbol of an atom. Explain the concept of average atomic mass. Atoms are the fundamental building blocks of all matter and are composed of protons, neutrons, and electrons. Because atoms are electrically neutral, the number of positively charged protons must be equal to the number of negatively charged electrons.
WebOne of the more common uses is as a tracer in which a radioisotope, such as technetium-99m, is taken orally or is injected or is inhaled into the body. The radioisotope then circulates through the body or is taken up only by certain tissues. Its distribution can be tracked according to the radiation it gives off.
