Question

Q.1. Read the passage given below.



1. For more than four exhausting years, the Polish-bom Marie Curie and her husband, Pierre,

worked in a large dilapidated wooden shed near their Paris lodgings. This shed, which was like a

hothouse in summer and draughty and cold in winter, was the place where they spent the

happiest years of their lives. It was here on a September night in 1902 that they finally

discovered the radioactive element that they named ‗radium‘ from the Latin word radius,

meaning ‗ray‘.

2. Radium provided the first effective treatment for some types of cancer, destroying the diseased

human cells by bombarding them with radioactive particles.

3. The Curies had spent the historic day pouring measures of purified pitchblende into some

6,000 evaporating bowls. Marie Curie believed that the black mineral ore contained a completely

new and dynamic element whose rays could destroy unhealthy body tissues. By constantly

filtering and re-filtering the pitchblende, she hoped that the elusive element would crystallize in

the bowls.

4. When they went home that evening the miracle had still not occurred. Then, just as they were

about to go to bed, Marie decided to have another look at the particles in the bowls. She and

Pierre hurried through the dimly-lit streets.

5. They let themselves into the darkened shed—with its rows of wooden tables and clutter of

laboratory equipment—and Marie asked Pierre not to light the lamps. They moved cautiously

forward and there, all around them, rays of light came from inside the small glass-covered bowls.

Marie turned to her husband and said quietly, ‗Do you remember the day you said to me: ―I

should like radium to have a beautiful colour?‖ Look … Look!‘

6. The bowls that lined the tables and the shelves on the walls gave off a soft, bluish-purple

glow.

1. Answer the following in one or two sentences.

(a) Who researched on radium and where?

(c) Why did they decide to name the element so?
