### (i) ( ^{234}\text{U} \rightarrow , ? \rightarrow ^{210}\text{Po} ) 1. Let the number of α-particles be (x) and β-particles be (y). 2. Mass number change: [ 234 - 4x = 210 \implies 4x = 234 - 210 = 24 \implies x = 6 ] 3. Atomic number change: Let Uranium atomic number (Z=92), Polonium (Z=84): [ 92 - 2x + y = 84 \implies 92 - 2(6) + y = 84 \implies 92 - 12 + y = __________ __________ _____ _____ _____ ______ __________ ___ _________ _____.
