In the nuclear equation $_{11}Na^{23} + _{1}H^{1} \to _{12}Mg^{23} + x$,what does $x$ represent?

In the nuclear reaction $_{92}U^{238} \to _{82}Pb^{206}$,the number of alpha and beta particles decayed are

If $_{92}U^{235}$ nucleus absorbs a neutron and disintegrates into $_{54}Xe^{139}$,$_{38}Sr^{94}$ and $X$,then what will be the product $X$?

For the reaction $^{14}N + \alpha \longrightarrow {}^{17}O + p$, $1.16 \ MeV$ (Mass equivalent $= 0.00124 \ amu$) of energy is absorbed. Mass on the reactant side is $18.00567 \ amu$ and proton mass $= 1.00782 \ amu$. The atomic mass of ${}^{17}O$ will be (in $amu$)

In the nuclear transmutation $_4^9 Be + X \longrightarrow _4^8 Be + Y$,the pair $(X, Y)$ is (are):

In the nuclear reaction $_7N^{14} + _2He^4 \to _ZX^A + _1H^1$,the product nucleus $_ZX^A$ formed is:
