He is the one who created the first version of the modern periodic table.<\/p>\n\n\n\n<p>When Mendeleev arranged elements based on their atomic masses, he noticed something interesting: elements with similar properties appeared at regular intervals. Mendeleev has its prediction on elements.<\/p>\n\n\n\n<p>Mendeleev left blank spaces in his periodic table where he thought undiscovered elements would go. He used the prefix \u201cEka-\u201d (from Sanskrit, meaning \u201cone\u201d) to name these elements. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eka-Boron: one place below boron<\/li>\n\n\n\n<li>Eka-Aluminium: one place below aluminium<\/li>\n\n\n\n<li>Eka-Silicon: one place below silicon<\/li>\n<\/ul>\n\n\n\n<p>He predicted their properties based on the elements above them in the periodic table. And when these undiscovered elements were discovered later, they were very similar to what Mendeleev had predicted.<\/p>\n\n\n\n<p>Now, let\u2019s understand Eka-Boron, Eka-Aluminium and Eka-Silicon one by one:<\/p>\n\n\n\n<p><strong>1. Eka-Boron:<\/strong> Mendeleev placed it below boron in Group 13. Later, it was discovered and named scandium (Sc). Scandium had many similar properties to boron, just as Mendeleev had predicted.<\/p>\n\n\n\n<p><strong>2. Eka-Aluminium: <\/strong>He placed this element just below aluminium in Group 13. It was discovered later and named gallium (Ga). Gallium has properties like a low melting point and reacts like aluminium. It matched Mendeleev\u2019s predictions almost exactly!<\/p>\n\n\n\n<p><strong>3. Eka-Silicon: <\/strong>This element came below silicon in Group 14. It was later discovered as germanium (Ge). Germanium showed properties like silicon and was used in electronics and semiconductors.<\/p>\n\n\n\n<p>The table below will help you to understand about these elements in an easy way:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Eka-Name<\/strong><\/td><td><strong>Actual Element<\/strong><\/td><td><strong>Group<\/strong><\/td><td><strong>Resembles<\/strong><\/td><\/tr><tr><td>Eka-Boron<\/td><td>Scandium (Sc)<\/td><td>3<\/td><td>Boron<\/td><\/tr><tr><td>Eka-Aluminium<\/td><td>Gallium (Ga)<\/td><td>13<\/td><td>Aluminium<\/td><\/tr><tr><td>Eka-Silicon<\/td><td>Germanium (Ge)<\/td><td>14<\/td><td>Silicon<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Let\u2019s look at why understanding these elements is important for students.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mendeleev\u2019s predictions showed that the periodic table is not random; it follows a logical pattern.<\/li>\n\n\n\n<li>It helped scientists believe in the periodic law, even before all elements were discovered.<\/li>\n\n\n\n<li>Today, the periodic table is one of the most powerful tools in chemistry.<\/li>\n<\/ul>\n\n\n\n<p><strong>Common Doubts of Chemistry:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-pale-ocean-gradient-background has-background has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-blue-vitriol\/\"><strong>What is Blue Vitriol?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-chemical-name-of-bleaching-powder\/\"><strong>What is the Chemical Name of Bleaching Powder?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/how-many-structural-isomers-are-possible-for-pentane\/\"><strong>How many Structural Isomers are Possible for Pentane?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-full-form-of-bhc\/\"><strong>What is the Full Form of BHC?<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"To understand Eka-Boron, Eka-Aluminium, and Eka-Silicon, we need to know about a renowned scientist, Dmitri Mendeleev.
