A nucleus emits 2 α particles and 1 β particle to form a nucleus. Find the atomic number and mass number of X.

Question

KnowledgeBoat · Accepted Answer

before the emission of β particle, would have atomic number 84, and before 2 α emissions, atomic number would have been 88. Hence, atomic number (Z) = 88. before the emission of β particle, would have mass number 222, and before 2 α emissions, mass number would have been 230. Hence, mass number (A) = 230.
