Actinium 231,`.^(231)AC_(89)`, emit in succession two `beta` particles, four `alpha`-particles, one `beta` and one `alpha` plus several `lambda` rays. What is the resltant isotope?

alpha -particles do more damage than beta -rays why?

What is the ratio of the charges of alpha and beta - particles?

In the actinium, series, the first member ._(92)U^(235) emits in succession 7 alpha particles and 4 beta particles and gets converted into a stable lead isotope lead isotope. Find the atomic number and mass number of the lead isotope so formed.

A nucleus "_n^mX emits one alpha -particles and two beta -particles. The resulting nucleus is:

A nucleus ._n X^m emits one alpha and one beta particles. The resulting nucleus is.

A nucleus ._n X^m emits one alpha and one beta particles. The resulting nucleus is.

A nucleus ._n^ m X emits one alpha- particle and two beta- particles. The resulting nucleus is

A nucleus ._n^ m X emits one alpha- particle and two beta- particles. The resulting nucleus is

A nucleus ._n^mX emits one alpha particle and two beta^- particles .The resulting nucleus is
