daughter atom मीनिंग इन हिंदी

The additional alpha particles from the daughter atoms can be deadly to nearby cells.
As it decays, actinium-225 produces three daughter atoms, each of which also gives out alpha particles.
If the mass difference between the parent and daughter atoms is more than 1.022 MeV / c 2 ( two electron masses ), another decay is accessible, capture of one orbital electron and emission of one positron.
If the energy difference between the parent atom and the daughter atom is less than 1.022 MeV, positron emission is forbidden as not enough decay energy is available to allow it, and thus electron capture is the sole decay mode.
If the mass difference between the mother and daughter atoms is more than two masses of an electron ( 1.022 MeV ), the energy released in the process is enough to allow another mode of decay : "'electron capture with positron emission " '.
