Question

234U has 92 protons and 234 nucleons total in its nucleus. It decays by emitting an alpha particle. After the decay it becomes (A) 232 U (B) 232 Pa (C) 230 Th (D) 230 Ra

Tardigrade Admin · Accepted Answer

Alpha particle has mass number 4 and atomic number 2 . Therefore, after emission of an alpha particle. The mass number of the 234 U will reduce by 4 and after decay it becomes 230 Ra

Q. $^{234} U$ has $92$ protons and $234$ nucleons total in its nucleus. It decays by emitting an alpha particle. After the decay it becomes

$^{232} U$

$^{232} P a$

$^{230} T h$

$^{230} R a$

Alpha particle has mass number $4$ and atomic number $2.$ Therefore, after emission of an alpha particle. The mass number of the $^{234} U$ will reduce by $4$ and after decay it becomes $^{230} R a$
