In a radioactive decay, neither the atomic number nor the mass number changes. Which of the following would be emitted in the decay process
Proton
Neutron
Electron
Photon
Which ray contain positively charged particle
In the disintegration series the $_{92}^{238}U\xrightarrow{\alpha }X\xrightarrow{{\beta - }}_Z^AY$ values of $Z$ and $A$ respectively will be
A plot of the number of neutrons $(N)$ against the number of protons ( $P$ )of stable nuclei exhibits upward deviation from linearity for atomic number, $Z>20$. For an unstable nucleus having $N / P$ ratio less than $1$ , the possible mode($s$) of decay is(are)
($A$) $\beta^{-}$-decay ( $\beta$ emission)
($B$) orbital or $K$-electron sasture
($C$) neutron emission
($D$) $\beta^{+}$-decay (positron emission)
What happens to the mass number and atomic number of an element when it emits $\gamma$-radiation?
In which radioactive disintegration, neutron dissociates into proton and electron
