Applications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Introduction: Welcome to today&#8217;s lesson! Today, we will be diving into the fascinating world of thorium. Thorium is a naturally occurring radioactive metal that belongs to the actinide series of elements on the periodic table. It was discovered in 1828 by the Swedish chemist J\u00f6ns Jacob Berzelius, and it gets its name from Thor, the Norse god of thunder.<\/p>\n\n\n\n<p>Thorium is often recognized for its potential as an alternative energy source due to its abundance and its ability to produce nuclear energy. It is estimated that thorium reserves are four times more abundant than uranium, which is commonly used in nuclear power plants. Additionally, thorium reactors have the potential to produce less long-lived radioactive waste compared to traditional uranium reactors.<\/p>\n\n\n\n<p>Now, let&#8217;s take a closer look at the key properties of thorium in the table below:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Atomic Number<\/th><th>Symbol<\/th><th>Atomic Weight<\/th><th>Valency<\/th><\/tr><\/thead><tbody><tr><td>90<\/td><td>Th<\/td><td>232.04 u<\/td><td>+4<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">key properties of thorium<\/figcaption><\/figure>\n\n\n\n<p>In the table above, you can see that thorium has an atomic number of 90, denoted by the symbol Th. Its atomic weight is approximately 232.04 atomic mass units (u). When it comes to valency, thorium typically exhibits a valency of +4, indicating that it can form compounds by losing four electrons.<\/p>\n\n\n\n<p>Thorium&#8217;s unique properties make it an interesting element to study and explore, not only for its potential as an energy source but also for its various applications in industries such as aerospace, medicine, and more. As we continue our journey through the world of science, we will delve deeper into thorium&#8217;s uses, properties, and its impact on our modern society.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Thorium_Discovery_Usage_and_Key_Points\"><\/span>Thorium : Discovery, Usage, and Key Points<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Discovery\"><\/span>Discovery: <span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Thorium was first discovered in 1828 by the Swedish chemist J\u00f6ns Jacob Berzelius. Berzelius isolated thorium oxide from a mineral sample called thorite, which was found in the Swedish island of L\u00f8v\u00f8ya. He named the newly discovered element &#8220;thorium&#8221; after Thor, the Norse god of thunder.
