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 83sr undergoes positron emission?
When strontium undergo positron emission, a proton
is converted to neutron, the sum of the proton in the atom decreased by one
while the total number of the nucleon does not change, therefore the daughter
nuclide formed is lead, with z =82.
