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 alpha decay of what isotope of what element produces lead-206?
the
decay equation should look as follows
? → 206
82Pb +42He
according
to alpha decay, the parent nuclei must haveatomic number of 84 and a mass number of 210 and this correspond with
polonium-210.
