Strontium-88 is the most abundant stable isotope of strontium.Strontium-90 is a particularly hazardous radioactive isotope because,as an alkali earth metal,it will substitute for calcium in bones and teeth.Predict its decay pathway.

Question

Quizplus · Accepted Answer

Strontium-90 undergoes beta decay, specifically beta-minus decay, meaning a neutron is converted into a proton and an electron. The emitted electron (beta particle) and an anti-neutrino leave the nucleus. This results in the element yttrium-90, which then undergoes further decay, including gamma decay and emissions of alpha particles and beta particles, until it reaches a stable isotope, zirconium-90. The specific decay pathway for strontium-90 includes the emission of a beta particle, an anti-neutrino, a gamma ray, and a positron. Therefore, the most accurate choice is B.
