When carbon-14 (14 6 C) transmutes into nitrogen-14 (14 7 N), it undergoes a type of radioactive decay known as beta decay, specifically, negative beta decay. In this process, a neutron inside the carbon-14 nucleus is converted into a proton while releasing an electron (known as a beta particle) and an antineutrino.
Here's the notation for the beta decay of carbon-14: 14 6 C → 14 7 N + e− + ν̅e
The e− symbol represents the electron (or beta particle) that is emitted, and ν̅e is the antineutrino. Since an electron is released, it is referred to as negative beta decay. The nitrogen-14 atom that is produced has one more proton than the original carbon-14 atom, which is why the element changes from carbon to nitrogen.
