To determine the age of fairly recent fossils and organic artifacts,it is possible to analyze the amounts of the isotopes 14C and 14N,because over time the 14C-which originated in the atmosphere-breaks down into 14N through a process known as beta decay.What net change occurred for this to happen?
A)The 14C lost an electron.
B)The 14C gained an electron.
C)The 14C lost a proton.
D)The 14C gained a proton.
E)The 14C gained a neutron.
