1.	In the decay series `._(92)U^(238)` to `._(82)Pb^(206)`, how many `alpha`-paritcles and how many `beta^(ɵ)`-particles are emitted?A. 6,8B. 9,6C. 8,8D. 8,6
Answer» Correct Answer - D `._(92)U^(238) rarr ._(82)Pb^(206) + x ._(2)He^(4) + y ._(-1)e^(0)` Equating mass number on both sides `238 = 206 + x xx 4 + y xx 0` `:. X = (238 - 206)/(4) = 8` Equating atomic number on both sides `92 = 82 + 2 xx 8 + y (-1)` `:. y = 98 - 92 = 6`
