krypton has
an atomic mass of 79 and an atomic number of 36, when it undergo a positron
decay , one of its proton decayed into a neutron, positron and an electron
neutrino. the number of protons decrease by one and so the atomic number
reduces by one, therefore the new atom will have an atomic number of 35 while the atomic mass remain constant because
the total number of nucleon does not change.
the daughter
nucleus will be bromine with atomic mass of 79 and a chemical symbol of Br.
