what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
what happens to the atomic number and mass number of a nucleus when it undergoes beta decay
the atomic number increases by one while the mass number remain
unchanged.in a beta decay, a neutron is
converted ton proton, an electron and an electron antineutrino.
