On bombarding $_8^{16}O$ with deuterons,the nuclei of the product formed will be

An element $_{96}X^{227}$ emits $4\alpha$ and $5\beta$ particles to form a new element $Y$. The atomic number and mass number of $Y$ are:

Artificial radioactivity was first discovered by

Artificial transmutation was discovered by

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 $amu$)
