After the emission of a \(\beta\)-particle followed by an \(\alpha\)-particle from \({ }_{83}^{214} \mathrm{Bi}\), the number of neutrons in the atom is -

If in case of a radio isotope the value of half-life (T\(_{1/2}\)) and decay constant (\(\lambda\)) are identical in magnitude, then their value should be

For the reaction \(_7^{14}N(\alpha ,p)\,{}^{17}O\), 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
