Show that `""_(92)^(238)U` can not spontaneously emit a proton. Given:
`""_(92)^(238)U` = 238.05079u, `""_(91)^(237)Pa` = 237.05121u `""_(1)^(1)H` = 1.00783u

Is it possible for ""_(92)U^(238) spontaneously to emit a proton? Given, atomic mass of ""_(92)U^(238), ""_(91)Pa^(237) and ""_(1)H^(1) is 238.05079 u, 237.05115 u and 1.00783 u respectively.

""_(92)^(235)U, ""_(92)^(238)U and ""_(92)^(239)U are

The number of electrons in ""_(92)U^(238) is

The partlcles emitted 1n the decay of ""_(92)^(238)U to ""_(92)^(234)U
