…undergoes double beta decay into ruthenium-100 with half-life 7.07×1018 years. All the synthetic isotopes of molybdenum decay into isotopes of niobium, technetium, or zirconium. The most stable of them is 93Mo, with a half-life of 4,839 years to electron capture, giving stable niobium. The most common isotopic…
