How many electrons in thorium 230
WebThorium exists in nature in a single isotopic form – Th-232 – which decays very slowly (its half-life is about three times the age of the Earth). The decay chains of natural thorium and uranium give rise to minute traces of Th-228, Th-230 and Th-234, but the presence of these in mass terms is negligible. It decays eventually to lead-208.

WebThe path of production of 234 U via nuclear decay is as follows: 238 U nuclei emit an alpha particle to become thorium-234. Next, with a short half-life, a 234 Th nucleus emits a beta particle to become protactinium-234. Finally, 234 Pa nuclei each emit another beta particle to become 234 U nuclei.
