what is the daughter nucleus produced when 63zn undergoes electron capture?

when the atomic number decreases by one while the atomic mass remain  unchanged  after an electron capture. where proton rich nucleus absorbs one of its inner electron and the proton change to neutron, one nuclear charge is lost while the , nucleon number remain constant and new atom is created with atomic number less than the parent atom by a value of one. for zinc Zn with atomic number of 30, with a loss of a proton, the atomic number will be 29 which is cupper.
