Improve your scientific vocabulary for higher band scores in IELTS reading and writing sections.<\/p>\n<p>Mastering advanced scientific vocabulary is crucial for achieving a high band score in IELTS, especially in the reading and writing sections.<\/p>\n<p>Today, we&#8217;re focusing on a term that&#8217;s fundamental in chemistry and nuclear physics: isotope.<\/p>\n<p><strong>Word type:<\/strong> Noun<\/p>\n<p>Isotope is pronounced as EYE-suh-tohp.<\/p>\n<p><strong>Meaning:<\/strong> An isotope is a variant of a particular chemical element.<\/p>\n<p>While all isotopes of an element have the same number of protons in their atomic nuclei, they differ in the number of neutrons.<\/p>\n<p>This means isotopes of an element have the same atomic number but different mass numbers.<\/p>\n<p><strong>Word history:<\/strong> The term isotope comes from the Greek words isos, meaning equal, and topos, meaning place.<\/p>\n<p>It was coined in 1913 by the British chemist Frederick Soddy, who recognized that certain elements existed in forms that were chemically identical but had different atomic masses.<\/p>\n<p>Isotopes play a significant role in various scientific fields. In nuclear physics, some isotopes are stable, while others are radioactive.<\/p>\n<p>Radioactive isotopes, also called radioisotopes, are used in medical treatments, carbon dating, and energy production.<\/p>\n<p><strong>Examples use in sentences:<\/strong> Carbon-14 is a radioactive isotope used in archaeological dating. The periodic table does not distinguish between different isotopes of an element.<\/p>\n<p>Scientists use mass spectrometry to separate and identify isotopes. Common errors in use: One common mistake is confusing isotopes with ions.<\/p>\n<p>While isotopes have different numbers of neutrons, ions have different numbers of electrons. Another error is assuming all isotopes are radioactive, which is not the case.<\/p>\n<p><strong>Synonyms:<\/strong> While there isn&#8217;t a direct synonym for isotope, related terms include nuclide and atomic variant.<\/p>\n<p><strong>Antonyms:<\/strong> There isn&#8217;t a true antonym for isotope, but contrasting terms might include element or compound, which refer to different aspects of atomic structure.<\/p>\n<p>Understanding and correctly using terms like isotope can significantly enhance your performance in the IELTS exam, particularly in tasks involving scientific topics.<\/p>\n<p>It demonstrates a sophisticated grasp of specialized vocabulary, a key factor in achieving a band score of 9.0.<\/p>","protected":false},"excerpt":{"rendered":"<p>IELTS Vocabulary: Understanding &#8216;Isotope&#8217; for Science Topics Learn about the term &#8216;isotope&#8217; for IELTS success.
