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?
the radioactive decay series of 238u terminates at which nonradioactive isotope?
the
natural decay series stops at lead, with atomic number 82, all other element
starting from atomic number 83 to 92 are naturally radioactive element.
