actinides's Usage Examples:

actinides, and is dangerously radiotoxic, requiring special custody, for 300,000 years.

5f electron to 6d, as is true also for the very late actinides: thus einsteinium, fermium, mendelevium, and nobelium were expected to be divalent metals.

Transactinide elements in the periodic table Z ≥ 104 (Rf) Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements.

actinides are f-block elements, corresponding to the filling of the 5f electron shell; lawrencium, a d-block element, is also generally considered an actinide.

In nuclear chemistry, the actinide concept proposed that the actinides form a second inner transition series homologous to the lanthanides.

followed by a complex process of separating einsteinium-253 from other actinides and products of their decay.

The minor actinides include.

scandium and yttrium only, or the inclusion of all 30 lanthanides and actinides in the group as well.

The early actinides (Th to Am) show some similarities to transition metals and have basic or amphoteric oxides; the late actinides are more like the.

solely to actinides; non-actinides such as radon and radium are of note.

the actinides (atomic number greater than 103).

minor actinides include neptunium (element 93), americium (element 95), curium (element 96), berkelium (element 97), californium (element 98), einsteinium.

Lanthanoids and actinoids are sometimes referred to as lanthanides and actinides respectively.
