← ScienceWhich consequence results when carbon-14 undergoes beta decay?
A)Nitrogen-14 concentration subsequently increases✓
B)Radioactivity ceases almost immediately
C)Emitted beta particles lack initial energy
D)Atomic mass increases above standard
💡 Explanation
During beta decay, a neutron converts into a proton emitting an electron and antineutrino. The atomic number increases because beta decay changes carbon into nitrogen-14; therefore, nitrogen presence is observed, rather than the isotope remaining stable.
