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 nuclide is formed when 211po undergoes α decay?
the nuclide formed is lead-207, two protons is
lost and two neuron is lost, four is lost from the mass number and two from the
atomic number of the daughter nuclide
