What is Periodic Table?
A periodic Table is the arrangement of all the elements in the known universe based on either atomic weight or atomic number. There are various failed attempts to arrange the known elements so that all the elements with similar properties are arranged together. But in 1863 Russian chemist Dmitri Mendeleev, gave Mendeleev’s Periodic Table which is the most successful attempt of that time. In modern-day, scientists using Mendeleev’s Periodic Table as a base created a long-form periodic table which is called Modern Periodic Table.
In this table, Periods are made up of elements that are organized horizontally (from left to right) and the group is made up of elements that are arranged vertically (from top to bottom). We’ll learn about the periodic trends in these periods and groups in this article.
Periodic Table Trends
Article with the name “Periodic Table Trends” as the name suggests explores the trends and patterns in the property of elements while arranged in the modern-day periodic table. Scientists in the early days observed that while arranging the elements based on either atomic weight or atomic number, elements with similar properties automatically got arranged closer to each other. This article will explore the same thing with the modern-day lens and will tell you about all the trends in various properties such as atomic radius, valency, metallic or non-metallic characters, reactivity, boiling point, melting point etc. So, let’s learn about these trends in the properties of elements while arranged in the periodic table.
