Hello students, in this question we are asked to write the decay equations for bromine -at.
00:08
It undergoes three decay processes that is beta minus decay, beta plus decay and electron capture.
00:39
In beta minus decay, the bromine atom decays to a, that is bromine -at decomposes to krypton plus proton, electron and an anti -neutrino.
01:33
Whereas in beta plus decay, the unstable bromine -at decomposes to a, that is selenium -34, at plus a neutron, positron and electron -neutrino.
02:23
Further, in electron capture, electron capture, the unstable bromine -at decomposes to capturer and electron from inner shell, thus becoming selenium -et -34 plus an electron -neutrino is emitted here, electron captured.

Further, in the second part of the question, we are asked to find out the decay energy, that is equation for decay energy q -beta is equal to delta m into 9315 mega electron moles...
