Electron Affinity Trend: Across the period (from left to right): IncreasesDown the group (from top to bottom): Decreases The electron affinity of elements increases as we move across a period (from left to right) and it decreases as we move down in a group (from top to bottom). Well this was just an introduction about … Read more
Electronegativity Trend: Across the period (from left to right): IncreasesDown the group (from top to bottom): Decreases The electronegativity of elements increases as we move across a period (from left to right) and it decreases as we move down in a group (from top to bottom). Well this was just an introduction about the electronegativity … Read more
Atomic Radius Trend: Across the period (from left to right): Decreases Down the group (from top to bottom): Increases The atomic radius (or atomic size) of the elements decreases as we move across a period (from left to right) and it increases as we move down in a group (from top to bottom). Well this … Read more

This single image is enough for you to remember all the major periodic trends of the periodic table. Let me explain the above image … Read more
Periods in periodic table are the horizontal rows on the periodic table. There are a total 7 horizontal rows on the periodic table, that means the periodic table has 7 periods. Let’s discuss each of these periods of periodic table one by one. Period 1: Shortest period The 1st period of the periodic table is … Read more
Periodic table groups are the vertical columns on the periodic table. There are a total of 18 groups (vertical columns) on the periodic table. Let’s discuss each of these groups of periodic table one by one. Group 1: Alkali metals Alkali metals are the group 1 elements present on the periodic table. Hydrogen is not … Read more
What are Heavy Metals? The metals that have higher density or higher atomic mass are known as heavy metals. Now there are different definitions of heavy metals according to different researchers. Because some researchers have defined the term heavy metals on the basis of metallurgy, some have defined it on the basis of physical properties … Read more
The inner transition metals are the elements that are found in the two rows which are at the bottom of the periodic table. The inner transition metals include; There are many important things to know about the inner transition elements of the periodic table. So let’s dive right into it. Table of contents Why are … Read more
Transition metals are the elements that are lying in the middle of the periodic table from group 3 to group 11. There are a total 31 commonly known transition metals on the periodic table. But many students have confusion regarding whether group 12 elements are transition metals or not? Also they have confusion whether lanthanum … Read more
Noble gases (also known as inert gases) are the elements on the periodic table that are located in the last column (group 18) on the periodic table. There are 6 known noble gases on the periodic table. Noble gases are highly unreactive which means they do not easily react with any other elements. Oganesson (Og) … Read more
