Below text how atoms were discovered is adapted from ielts-up just to give an example for IELTS reading sentence completion.

How atoms were discovered Hundreds of years ago in 1785 Dutch scientist Jan Ingenhousz was studying a strange phenomenon that he couldn’t quite make sense of. Minute particles of coal dust were darting about on the surface of some alcohol in his lab. About 50 years later, in 1827, the Scottish botanist Robert Brown described something curiously similar. He had his microscope trained on some pollen grains. Brown noticed that some of the grains released tiny particles – which would then move away from the pollen grain in a random jittery dance.
At first, Brown wondered if the particles were really some sort of unknown organism. He repeated the experiment with other substances like rock dust, which he knew wasn’t alive, and saw the same strange motion again. It would take almost another century for science to offer an explanation. Einstein came along and developed a mathematical formula that would predict this very particular type of movement – by then called Brownian motion, after Robert Brown. Einstein’s theory was that that the particles from the pollen grains were being moved around because they were constantly crashing into millions of tinier molecules of water – molecules that were made of atoms. By 1908, observations backed with calculations had confirmed that atoms were real. Within about a decade, physicists would be able to go further. By pulling apart individual atoms they began to get a sense of their internal structure. It might come as a surprise that atoms can be broken down – particularly since the very name atom derives from a Greek term “atomos”, which means “indivisible”. But physicists now know that atoms are not solid little balls. It’s better to think of them as tiny electrical, “planetary” systems. They’re typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system. The electrons orbit this nucleus, like planets.

Questions and their answers with explanation

  1. The type of random jittery movement of tiny particles is called ________.

After reading the sentence, use the skimming and scanning technique to find the keywords, you find in the question sentence type of random jittery movement. You can see in the 3rd passage of the above text in which you have to face the keyword “type of movement”. It is your location of answer; not the exact answer of the question. Read the sentence carefully and understand the meaning of sentence.

So, the answer you find will be Brownian motion, place it to question sentence and make sense in the question.

  • Einstein explained the phenomenon of particles’ strange motion by the fact that they were collapsing with _____________.

In this question sentence, Einstein and particles phenomenon are keywords to identify in the text for getting correct answer. After reading the text, the fourth passage of the text says about the same topic and the keywords are also there to get correct answer. You have to check the synonyms of the words.

You can see, ‘water molecules’ is the correct answer to put it in the blank space. Because the exact words molecules of water are there in the text but you have to remember the instructions in which it is mentioned that “NO MORE THAN TWO WORDS”. So, you have to change these words in required word limit which is water molecules.

  • Nowadays, scientists consider atoms’ structures similar to tiny __________.

In this 3rd question, you can easily find the question’s keywords scientists and atom structure. Now turn to the text side and find these keywords. It is easy to see atom structure keyword in the last passage of the text. The last passage is the paraphrased of question statement. The correct answer is planetary systems.

  • _____________ are parts that are circling around the nucleus.

Nucleus is the keyword in this question sentence. As you know well that in this question type, the questions and answers are in same order, so the answer of this question is in the last passage of the text and after the 3rd answer. In the last line of the passage, you can face the word nucleus which tells you right answer for this question i.e., electrons.
