Isotopes of antimony

{{Short description|none}}

{{Infobox antimony isotopes}}

Antimony ({{sub|51}}Sb) occurs in two stable isotopes, {{sup|121}}Sb and {{sup|123}}Sb. There are 37 artificial radioactive isotopes, the longest-lived of which are {{sup|125}}Sb, with a half-life of 2.75856 years; {{sup|124}}Sb, with half-life 60.2 days; and {{sup|126}}Sb, with half-life 12.35 days. All other isotopes have half-lives less than 4 days, most less than an hour. There are also many isomers, the longest-lived of which is {{sup|120m1}}Sb with half-life 5.76 days.

Except for beryllium, antimony is the lightest element observed to have isotopes capable of alpha decay; {{sup|104}}Sb is seen to undergo this mode of decay. Some light elements, namely those near Beryllium-8, have isotopes with delayed alpha emission (following proton or beta emission) as a rare branch.
