In this brief introduction, we will explore the key characteristics and properties of holmium, along with its atomic number, symbol, atomic weight, and valency. By the end of this lesson, you will have a deeper understanding of this unique element and its significance in various fields of science.<\/p>\n\n\n\n<p>Holmium is a rare earth metal that belongs to the lanthanide series in the periodic table. Its atomic number is 67, and its symbol is Ho, derived from the Latin word &#8220;Holmia&#8221; which means Stockholm. Discovered by Swedish chemist Per Teodor Cleve in 1878, holmium is named after the city where it was first identified.<\/p>\n\n\n\n<p>Table: Properties of Holmium<\/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>67<\/td><td>Ho<\/td><td>164.93032<\/td><td>+3<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Properties of Holmium<\/figcaption><\/figure>\n\n\n\n<p>Holmium possesses a relatively high atomic weight of approximately 164.93032 atomic mass units (u). It is a silver-white, lustrous metal that is soft and malleable. Holmium is classified as a rare earth element due to its occurrence in the Earth&#8217;s crust, although it is not as abundant as some other elements in this group.<\/p>\n\n\n\n<p>One of the notable properties of holmium is its magnetic nature. It is highly paramagnetic, meaning it demonstrates a strong attraction to magnetic fields. This property makes holmium crucial in the development of magnets and other magnetic applications.<\/p>\n\n\n\n<p>When it comes to valency, holmium predominantly exhibits a valency of +3. Valency refers to the number of electrons an atom can gain, lose, or share to attain a stable configuration. With three valence electrons, holmium readily forms chemical bonds with other elements to achieve a more stable state.<\/p>\n\n\n\n<p>In conclusion, holmium is a rare earth metal with an atomic number of 67 and symbol Ho. It has an atomic weight of approximately 164.93032 and primarily exhibits a valency of +3. This versatile element plays a significant role in various fields, including magnetism and scientific research. Stay tuned for future lessons where we delve deeper into the fascinating world of the periodic table.<\/p>\n\n\n\n<p>Remember to practice the periodic table regularly and explore the unique properties of different elements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Holmium_Discovery_Usage_and_Key_Points\"><\/span>Holmium: 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_of_Holmium\"><\/span>Discovery of Holmium:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p> Holmium was discovered by Swedish chemist Per Teodor Cleve in 1878.
