actinide

Also known as actinoid, actinide series, actinide elements, actinides

The actinide () or actinoid () series encompasses at least the 14 metallic chemical elements in the 5f series, with atomic numbers from 89 to 102, actinium through nobelium. Number 103, lawrencium, is also generally included despite being part of the 6d transition series. The actinide series derives its name from the first element in the series, actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide.

AI overview

Actinides are a group of at least 14 metallic chemical elements with atomic numbers 89 to 102, named after actinium, the first element in the series. These elements are important in chemistry and physics because they have unique properties related to their position in the periodic table, and they include elements like uranium and plutonium that have significant practical and scientific applications.

The 1985 IUPAC Red Book recommends that actinoid be used rather than actinide, since the suffix -ide normally indicates a negative ion. However, owing to widespread current use, actinide is still allowed.
