They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

Questo decadimento è accompagnato con l'emissione di particelle come elettroni (conosciuti anche come particelle beta) e particelle alfa.

Isotopes participate in the same chemical reactions but often at differing rates.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

Ninety-nine percent of these also contain six neutrons.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.
