in alpha decay, the atomic no decreases by 2 and in beta decay, the atomic no increases by 1
so, let z the atomic no of the nucleus. when the nucleus emits alpha particle, the atomic no becomes z-2 and when it emits 2 beta particles, the atomic no increases by 2*1=2. so the final atomic no is z-2+2 which is z. so the initial and final nuclei are isotopes
