जब alpha-कण के उत्सर्जन के साथ _(92)^(232)U (द्रव्यमान = 232.037146 u है) क्षयित होकर _(90)^(228...

By using the following atomic masses : ._(92)^(238)U = 238.05079u . ._(2)^(4)He = 4.00260u, ._(90)^(234)Th = 234.04363u . ._(1)^(1)H = 1.007834, ._(91)^(237)Pa = 237.065121u (i) Calculate the energy released during the alpha- decay of ._(92)^(238)U . (ii) Show that ._(92)^(238)U cannot spontaneously emit a proton.

Consider the following nuclear decay: (initially .^(236)U_(92) is at rest) ._(92)^(236)rarr._(90)^(232)ThrarrX Following atomic masses and conversion factor are provided ._(92)^(236)U=236.045 562 u , ._(90)^(232)Th=232.038054 u , ._(0)^(1)n=1.008665 ,. _(1)^(1)p=1.007277 u , ._(2)^(4)He=4.002603 u and 1 u=1.5xx10^(-10)J The amount of energy released in this decay is equal to:

The atomic mass of uranium ._(92)^(238)U is 23.058 u , that of throium ._(90)^(234)Th is 234.0436 u and that of an alpha particle ._2^4He is 4.006 u , Determine the energy released when alpha-decay converts ._(92)^(238)U into ._(92)^(238) U . int ._(90)^(234)Th .
