The periodic table is a fundamental tool in chemistry that organizes elements based on their properties and atomic structure. Recently, four new elements have been officially recognized and added to the periodic table: nihonium, moscovium, tennessine, and oganesson. These elements are synthetic, meaning they are not found naturally on Earth, and have unique properties that expand our understanding of the periodic table.
Before we dive into the answers, it is essential to understand the context in which this reading passage appears. “A Buzz in the World of Chemistry” is an passage, but versions of it also appear in the IELTS General Reading test. The passage discusses a revolutionary approach in chemical research known as combinatorial chemistry , which has been a “buzz term” in industries like pharmaceuticals, agrochemicals, and biotechnology.
The text defines combinatorial chemistry as a "branch" of traditional chemistry, where the synonym completes the summary. 2. "In Vogue" Trends (Paragraph A) a buzz in the world of chemistry reading answers with
TRUE (It became the "rage" in the fashion capitals of the world). Questions 10–13: Short Answer/Completion
(Filling in the blanks based on the research of Daly and Shields) Fruit flies (Used in experiments regarding scent and behavior) (The source of certain alkaloids studied by Daly) (Specifically the Poison Dart frog species) Painkillers (The medical application of the discovered epibatidine) Antibiotics (Potential use for the peptides found in frog skin) Questions 12–13: Multiple Choice The periodic table is a fundamental tool in
You do not need a PhD in chemistry to answer these questions. The IELTS reading section tests , not scientific knowledge. When you see technical terms like “polypropylene mesh sacs” (Answer 7) or “thermal sealing” (Answer 8), treat them as signposts. Just find them in the text. Do not worry about what they mean scientifically.
The answers in the reading passage are rarely word-for-word copies of the questions. The exam tests your ability to recognize synonyms and paraphrased ideas. Notice how "buzz terms" in the text becomes "in vogue" in the question list, and "branch" becomes "offshoot." Regularly practice matching synonyms and rephrasing ideas from passages to prepare for this essential skill. Before we dive into the answers, it is
Green chemistry, also known as sustainable chemistry, is an area of research that focuses on reducing the environmental impact of chemical products and processes. This field has gained significant attention in recent years, as concerns about climate change, pollution, and sustainability have grown. Green chemists aim to design and develop products and processes that are more environmentally friendly, using renewable resources and minimizing waste.
: It allows scientists to create a virtually limitless number of molecular variations (e.g., peptide chains formed from various combinations of amino acids) to test for potential medical breakthroughs rapidly. Verified Answer Key & Textual Explanations
