Question

What is the speciality of lactinides ??​

Answer 1

Answer:

The actinoids are unusual in forming a series of 15 elements having no stable isotopes; every actinoid isotope undergoes radioactive decay, and, as a result, only a few of the lighter, stabler members of the series (such as thorium and uranium) are found in nature.

Answer 2

Actinides are a series of elements coming inside the f-block.

• The actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.
• The actinide series derives its name from the first element in the series, actinium.
• All are radioactive, highly electropositive, they tarnish readily in air.
• Actinides are very dense metals with distinctive structures. They react with boiling water or dilute acid to release hydrogen gas.
• Actinide metals tend to be fairly soft.
