Answer: O 10.1 is your answer! Please mark me as brainlyest!?
Precise and Accurate mean the same thing. I would consider measuring more than once to get a precise or accurate measurement.
7 protons , 7 neutrons , 2,5 electrons.
Cobalt-60 has 27 protons (thus 33 neutrons). If an inter-nucleus neutron decays and emits an electron, this neutron transforms into a proton. Now we have 28 protons and 32 neutrons.
