`._(92)^(238)U` has 92 protons and `238` nucleons. It decays by emitting an alpha particle and becomes:

.^(234)U has 92 protons and 234 nucleons total in tis nucleus. It decays by emitting an alpha particle. After the decay it becomes:

In the transformation of ""_(92)^(238)U to ""_(92)^(234)U , if one emission is an alpha -particle, what should be the other emission ?

In the transformation of ""_(92)""^(238)U to ""_(92)""^(234)U , if one emission is an alpha particle, what should be the other emission(s)?

""_(92)^(238)U is known to undergo radioactive decay to form ""_(82)^(206)Ph emitting alpha and beta particles. A rock initially contained 68xx10^(-6)g of ""_(92)^(238)U . If the number of alpha particles that it would emit during its radioactive decay of ""_(92)^(238)U to ""_(82)^(206)Pb in three half - lives is Zxx10^(18) , then what is value of Z?

At a result of radioactive decay a ._(92)^(238)U nucleus is changed to a ._(91)^(234)P nucleus. Which particles are emitted in the decay?
