WebbFrom the periodic table, we see that the atomic number (number of protons) for the element carbon is 6. The name carbon-14 tells us that this isotope's mass number is 14. The chemical symbol for carbon is C. Now write the isotopic notation for carbon-14. 14 6 C We can determine the number of neutrons as 14 −6 = 8 neutrons. Example 2. WebbDenoted by the chemical symbol Pu, it has 17 isotopes with mass numbers ranging from 227 to 248 of which Pu-224 is the most stable having a half-life of 80.8 million years [1] …

Plutonium Properties (25 Facts You Should Know)

WebbIn such an equation, the number of nucleons (protons + neutrons) is conserved, e.g. 235 + 1 = 141 + 92 + 3, but a small loss in atomic mass may be shown to be equivalent to the energy released. Webb29 mars 2024 · Appearance of plutonium: Silvery white appearance: Atomic number of plutonium: 94: Symbol of plutonium: Pu: Atomic mass of plutonium (most stable … WebbSince protons and neutrons have roughly the same mass, the more common version of carbon is called carbon-12 (6 protons + 6 neutrons). The heavier isotope is called carbon-14 (6 protons + 8 neutrons). But when you look up the mass of carbon on the periodic table, it says that the mass is 12.011 atomic mass units (amu). ospi school supplies
