A radioactive nucleus is represneted by the symbol _bX^a ,How is the new ucleus represented after the emission of a beta particle

A radioactive nucleus is represneted by the symbol _bX^a ,How is the new ucleus represented after the emission of a gamma ray photon?

Does the ratio of neutrons to protons in a nucleus increase, decrease or remain the same after the emission of alpha-particl es .

Does the ratio of neurtons to protons in a nucleus increase, decrease or remain the same after the emission of beta-particl es .

A radioactive nucleus undergoes a series of decays according to the sequence, A overset (beta) rarr A_1 overset (alpha) rarr A_2 overset (alpha) rarr A_3 If the mass number and atomic number of A_3 are 172 and 69 respectively,what is the mass number and atomic number of A?

Mohan deposits Rs. 2,000 in his bank account and withdraw Rs. 1,642 from it, the next day. If withdrawal of amount from the account is represented by a negative integer, then how will you represent the amount deposited? Find the balance in Mohan's account after the withdrawal.

The nucleus of an atom of ._(92)Y^(235) initially at rest decays by emitting an alpha particle. The binding energy per nucleon of parent and dougther nuclei are 7.8MeV and 7.835MeV respectively and that of alpha particles is 7.07MeV//"nucleon". Assuming the dougther nucleus to be formed in the unexcited state and neglecting its share of energy in the reaction, calculate speed of emitted alpha particle. Take mass of alpha particle to be 6.68xx10^(-27)kg .
