1.Describe what happens to a carbon-11 atom when it undergoes
positron emission.
The decay of a carbon-11 atom _____(options;changes a nuetron
into proton, changes proton into neutron, is hit with a neutron,
reconfigures its protons and neutrons) and this causes it to
emit______(options; a negatively charged electron sized particle, a
positively charged electron sized partticle, two atoms and several
neutrons, two neutrons and two protons)
