Mendeleev’s Periodic Table

In 1871, Dimtri Mendeleev also tried to arrange elements in periodic order. In 19th century, his element arrangement was most successful as compared to early attempts made by other scientists like Dobereiner and Newland. In this session we will discuss about following topics: 1. Mendeleev’s Periodic Table 2. Mendeleev’s Periodic Table Achievements 3. Mendeleev’s Periodic…

Early Attempts – Classification of Elements

In early 19th Century, many scientists made number of attempts to arrange and classify elements based on their elemental properties. Some of these classification are important: 1. Johann Dobereiner Triad Model 2. Newland’s Law Of Octaves Before going in for discussion on these model’s, It’s better to have basic understanding of few concepts & terms…

Rancidity

Rancidity is a process that is based on concept of oxidation & reduction. In previous session, we discussed about the process of corrosion, which was also based on oxidation. Related concepts like oxidation, reduction and redox reaction can be learned from previous sessions. Previous learning sessions: Oxidation Reduction Reaction Oxidation Reduction Example Redox Reaction Rancidity…

Corrosion

Corrosion is a process that is based on concept of oxidation. In previous sessions, we have discussed about the oxidation & reduction, including the reactions based on this known as Redox reactions. Previous learning sessions: Oxidation Reduction Reaction Oxidation Reduction Example Redox Reaction Corrosion   Corrosion is a kind of oxidation reaction in which Iron…

Oxidation-Reduction & Redox Reactions

In earlier sessions, we learned that a chemical reaction takes place on the basis of loss or gain or sharing of electrons between different elements taking part in that reaction. Because of this loss, gain or sharing of electrons, element changed its state and charge on it, either the charge goes positive or negative based…

Single & Double Replacement Reactions

There are four different types of chemical reactions. In previous session, we discussed about: 1. Combination or Synthesis Reactions 2. Decomposition Reactions In this session, We will focus on remaining two types of chemical reactions. 3. Single Replacement Reactions 4. Double Replacement Reactions Previous learning sessions: Why Chemical Reaction Took Place How to Balance Chemical…
