The number of `alpha`-particles emitted by
`""_(84)^(218)Ra rarr ""_(82)^(206)Pb` is

The number of a-particles emitted by ""^(218)Ra in changing to stable isotope ""^(206)Pb is :

The number of a particles emitted by ._84^218Ra in changing to stable isotope ._82^206Pb is

Calculate number of alpha-and beta - particles emitted when ""_(92)^(238)U changes into radioactive ""_(82)^(206)Pb

The kinetic energy of alpha -particle emitted in the alpha -decay of ""_(88)Ra^(266) is [given, mass number of Ra = 222 u]

The difference between number of alpha and beta particles emitted during the conversion of U_(92)^(238) to Pb_(82)^(206) is
