Number of electrons are lost by an atom in a chemichl reaction
Only one electron lost.
Because electrons, which are gained or lost to form ions from atoms, have so little mass compared with protons or neutrons that the electrons are ignored in the mass number.
Often there are the same number of electrons as there are protons. Exceptions to this are called ions, which have gained or lost an electron (can't be a proton lost or gained, that would change the element).
The charge an element would have if it lost or gained electrons
