Ow many neutrons are in the isotope lithium-8
WebJul 13, 2024 · The isotope whose atomic weight is 23.985 amu has a mass number of 24 (protons and neutrons), so 24 - 12 protons gives 12 neutrons. The symbol for this isotope is 24Mg. Similarly, the isotope whose atomic weight is 24.986 amu has a mass number of 25, 13 neutrons, and 25Mg as a symbol. WebNeutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons). These two alternate forms of carbon are isotopes. Some isotopes are stable, but others can emit, or kick out, subatomic particles to reach a more stable, lower-energy, configuration.
