ABSTRACT
Actinide Elements, or Actinides, a series of 15 chemical elements (atomic numbers 89 through 103). The series is named after actinium, the first element of the group. The other actinides, in order of increasing atomic number, are thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, and lawrencium. The actinides with atomic numbers higher than 92 (neptunium through lawrencium) are also called transuranium elements.
