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 is the daughter nucleus produced when 188hg undergoes positron emission?
When mercury undergo positron decay, the atomic
number decrease by one while the atomic mass remain unchanged. The daughter
nuclide formed is gold with atomic number of z =79.
