Chapter 1.6: Isotopes and Atomic Masses - Chemistry LibreTexts

WebThe atomic mass unit (u or amu) is a relative unit based on a carbon-12 atom with six protons and six neutrons, which is assigned an exact value of 12 amu's (u's). This is the standard unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. This is obviously very small. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g. WebMay 10, 2024 · If the mass number of an isotope is known, the actual number of neutrons can be calculated. Use the same formula, mass number minus atomic number, to calculate the number of neutrons. In the case of mercury, the most common isotope is mercury-202. Use the equation, 202-80=122, to find that mercury-202 has 122 neutrons. pinpoint spotsWebThe specific charge of an electron is 1.6⋅10 ^-19.
