Answer 2

ACTINIDES

In addition to uranium, (D) Thorium is the other actinide which occurs naturally in significant amounts.

GETTING TO KNOW MORE ABOUT ACTINIDES:

* Except for the final actinide (lawrencium), which is a d-block element, all of the actinides are f-block elements. Actinium has been classified as d-block instead of lawrencium on occasion, however those who examine the topic prefer the classification with lawrencium in the d-block.

* All actinides are radioactive and release energy as they decay; the most numerous actinides on Earth are naturally occurring uranium and thorium, as well as synthetically generated plutonium.

* Nuclear reactors and nuclear weapons both employ them. Americium is utilized in the ionization chambers of most contemporary smoke detectors, and uranium and thorium have a variety of present or historical uses.
