What is the meaning of actinoid?
Actinoids or actinides are 15 consecutive chemical elements in the periodic table from actinium to lawrencium (atomic numbers 89103). As a group, they are significantly large because of their radioactivity. Although several members of the group, including uranium (the most familiar), occur naturally, most are man-made.
