Let us consider emission of `alpha`particle from uranium nucleus:
`._(92)^(235)U – ._(2)He^(4) to ._(90)Th^(231)`
`{:(e = 92, e = 0, e = 90),(p = 92, p = 2, p = 90),(n = 143, n = 2, n = 141):}`
shortage of two electorns in thorium is due to:
A. conversion of electrons to positron
B. combination with positron to evolve energy
C. annihilation
D. absorption in the nucleus
