It helps students understand the elements that make up everything around us. More than just a chart, it shows how elements behave and interact with each other. The periodic table was first arranged by <strong>Dmitri Mendeleev<\/strong> in 1869, who organised the elements based on their atomic masses and discovered that elements with similar properties appeared at regular intervals. By learning the periodic table, students can discover patterns and connections that make chemistry easier to understand.<\/p>\n\n\n\n<p>Mastering the periodic table also prepares KS3 students for advanced topics like reactivity, bonding, and material classification. It not only improves exam performance but also sparks curiosity about the world around them.<\/p>\n\n\n\n<p>In this blog, we\u2019ve summed up everything you need to know about the periodic table at KS3. Let\u2019s dive in and make learning easy and enjoyable!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the Structure of the Periodic Table KS3?<\/h2>\n\n\n\n<p>What does the periodic table show? the periodic table organises elements into rows (called periods) and columns (called groups), helping us understand their relationships. Let\u2019s break it down:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"850\" height=\"567\" src=\"https:\/\/edumentors.co.uk\/blog\/wp-content\/uploads\/2025\/01\/Periodic-Table-ks3-1.jpg\" alt=\"periodic table ks3\" class=\"wp-image-18291\" style=\"width:690px\" srcset=\"https:\/\/edumentors.co.uk\/blog\/wp-content\/uploads\/2025\/01\/Periodic-Table-ks3-1.jpg 850w, https:\/\/edumentors.co.uk\/blog\/wp-content\/uploads\/2025\/01\/Periodic-Table-ks3-1-300x200.jpg 300w, https:\/\/edumentors.co.uk\/blog\/wp-content\/uploads\/2025\/01\/Periodic-Table-ks3-1-768x512.jpg 768w, https:\/\/edumentors.co.uk\/blog\/wp-content\/uploads\/2025\/01\/Periodic-Table-ks3-1-728x485.jpg 728w\" sizes=\"(max-width: 850px) 100vw, 850px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Periods (Rows)<\/h3>\n\n\n\n<p>The periodic table has <strong>7 periods<\/strong>. As you move across a period from left to right, the atomic number of elements increases. This means that elements become less metallic and more non-metallic as you move across the table.<br>For example, in Period 1, the first element is hydrogen (H), and the last element is neon (Ne). Hydrogen is a gas and a non-metal, while neon is a noble gas, also a non-metal, but with very different properties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Groups (Columns)<\/h3>\n\n\n\n<p>The periodic table has <strong>18 groups<\/strong>. Elements in the same group share similar chemical properties because they have the same number of electrons in their outer shell.<br>For example, Group 1 contains the <strong>alkali metals<\/strong>, like lithium (Li) and sodium (Na). These metals are highly reactive and share similar properties, like reacting with water.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Metals, Non-Metals, and Metalloids<\/h3>\n\n\n\n<p>The periodic table is also divided into metals, non-metals, and metalloids (elements that have properties of both metals and non-metals).<br>Metals are mostly on the left and centre, while non-metals are on the right side of the table. Metalloids, such as silicon (Si), sit between metals and non-metals.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Transition Metals<\/h3>\n\n\n\n<p>The transition metals are found in the middle of the table, between groups 2 and 3. These elements have special properties, such as being good conductors of heat and electricity. <\/p>\n\n\n\n<p>Understanding the structure of the periodic table helps KS3 students predict the properties of elements. This makes learning chemistry easier and more logical. It also shows how elements are connected and why some behave similarly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Groups in the Periodic Table KS3<\/h2>\n\n\n\n<p>Now that we\u2019ve looked at the structure of the periodic table. let&#8217;s take a look at three important groups that every<a href=\"https:\/\/edumentors.co.uk\/blog\/what-is-key-stage-3-an-in-depth-look\/\" target=\"_blank\" rel=\"noopener\" title=\" KS3 \"> KS3 <\/a>student should know:<\/p>\n\n\n\n<div class=\"wpdt-c row wpDataTableContainerSimpleTable wpDataTables wpDataTablesWrapper\n\"\n    >\n        <table id=\"wpdtSimpleTable-155\"\n           style=\"border-collapse:collapse;\n                   border-spacing:0px;\"\n           class=\"wpdtSimpleTable wpDataTable\"\n           data-column=\"4\"\n           data-rows=\"4\"\n           data-wpID=\"155\"\n           data-responsive=\"0\"\n           data-has-header=\"0\">\n\n                    <tbody>        <tr class=\"wpdt-cell-row \" >\n                                <td class=\"wpdt-cell wpdt-bold wpdt-tc-000000 wpdt-bc-C322DE\"\n                                            data-cell-id=\"A1\"\n                    data-col-index=\"0\"\n                    data-row-index=\"0\"\n                    style=\" width:18.65671641791%;                    padding:10px;\n                    \"\n                    >\n                                        Group                    <\/td>\n                                                <td class=\"wpdt-cell wpdt-bold wpdt-tc-000000 wpdt-bc-C322DE\"\n                                            data-cell-id=\"B1\"\n                    data-col-index=\"1\"\n                    data-row-index=\"0\"\n                    style=\" width:18.65671641791%;                    padding:10px;\n                    \"\n                    >\n                                        Elements                    <\/td>\n                                                <td class=\"wpdt-cell wpdt-bold wpdt-tc-000000 wpdt-bc-C322DE\"\n                                            data-cell-id=\"C1\"\n                    data-col-index=\"2\"\n                    data-row-index=\"0\"\n                    style=\" width:35.44776119403%;                    padding:10px;\n                    \"\n                    >\n                                        Properties                    <\/td>\n                                                <td class=\"wpdt-cell wpdt-bold wpdt-tc-000000 wpdt-bc-C322DE\"\n                                            data-cell-id=\"D1\"\n                    data-col-index=\"3\"\n                    data-row-index=\"0\"\n                    style=\" width:27.238805970149%;                    padding:10px;\n                    \"\n                    >\n                                        Example                    <\/td>\n                                        <\/tr>\n                            <tr class=\"wpdt-cell-row \" >\n                                <td class=\"wpdt-cell wpdt-bold wpdt-tc-000000 wpdt-bc-C322DE\"\n                                            data-cell-id=\"A2\"\n                    data-col-index=\"0\"\n                    data-row-index=\"1\"\n                    style=\"                    padding:10px;\n                    \"\n                    >\n                                        Group 1: Alkali Metals                    <\/td>\n                                                <td class=\"wpdt-cell wpdt-tc-000000 wpdt-bc-FFFFFF\"\n                                            data-cell-id=\"B2\"\n                    data-col-index=\"1\"\n                    data-row-index=\"1\"\n                    style=\"                    padding:10px;\n                    \"\n                    >\n                                        Lithium, Sodium, Potassium                    <\/td>\n                                                <td class=\"wpdt-cell wpdt-tc-000000 wpdt-bc-FFFFFF\"\n                                            data-cell-id=\"C2\"\n                    data-col-index=\"2\"\n                    data-row-index=\"1\"\n                    style=\"                    padding:10px;\n                    \"\n                    >\n                                        Highly reactive, especially with water.
