Answer on Question#59722 - Physics - Nuclear Physics

Complete the nuclear equations below. Which of them is an incorrect nuclear equation?

121SB->121Sn+-1B

238U->234Th+4/2a

10Be->10B+0/-1B

190Pt->186Os+4/2a

Answer:

$^{121}Sb \rightarrow {}^{121}Sn + e^+ + \gamma_e$ this is incorrect because this is $\beta^+$ decay

$^{238}U \rightarrow {}^{234}Th + {}^{4}He$

$^{10}Be \rightarrow {}^{10}S B + e^{-} + \overline{\gamma e}$

$^{190}Pt \rightarrow {}^{186}Os + {}^{4}He$
