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 WebMagnesium: Symbol: Mg: Atomic Number: 12: Atomic Mass: 24.305 atomic mass units: Number of Protons: 12: Number of Neutrons: 12: Number of Electrons: 12: Melting …
WebSolution. There are 12 protons in all magnesium isotopes. The isotope whose atomic weight is 23.985 u has a mass number of 24 (protons and neutrons), so 24 - 12 protons gives 12 neutrons. The symbol for this isotope is 24 Mg. Similarly, the isotope whose atomic weight is 24.986 amu has a mass number of 25, 13 neutrons, and 25 Mg as a … WebThe end of the stable elements in the periodic table occurs after lead, largely due to the fact that nuclei with 128 neutrons—two neutrons above the magic number 126—are extraordinarily unstable and almost immediately shed alpha particles.
