Web22 sep. 2024 · Ga-69 has 31 protons (as all gallium atoms) and 38 neutrons. Ga-70 has 39 neutrons, Ga-71 has 40 neutrons. In general, pairing of protons and neutrons makes nuclei stable, so the Ga-70 as an unpair/unpair nucleus is unstable with respect to beta-emitting, yielding Ge-70, which is paired/paired. Is gallium stable or unstable? Web4 aug. 2024 · In this case, the first isotope Gallium - 69 has an atomic mass of 69 and a percent natural abundance of X%. The second isotope Gallium - 71 has an atomic mass of 71 and a percent natural abundance of (100-X)%. On the other hand, the Relative Atomic Mass of Gallium is 69.8. Then, the value of X can be calculated as: 69× X+ 71× (1-X)= … highlight and contour pro palette

WebThe total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. WebAbout Gallium-71 Metal Isotope.
