PERIODIC TABLE

 Modern Periodic table Modern Periodic Law :  The recent work has established that the fundamental property of an atom is atomic number and not atomic weight. Therefore, atomic number is taken as the basis of the classification of the elements. The modern periodic law was given by Moseley, it may be stated as : ''The properties of elements are periodic functions of their atomic number". Modern periodic table is also called long form of the periodic table or Bohr’s table. In this table, the elements are arranged in order of their increasing atomic number. It consists of 4 blocks (s, p, d and f), 18 groups numbered from 1 to 18 and 7 periods numbered from 1 to 7. Short tricks to learn periodic table  Blocks : The periodic table is divided into four main blocks (s, p, d and f) depending upon the subshell to which the valence electron enters into.  (1) Elements of group 1 and 2 constitute s-Block.   (2) Elements of group 13, 14, 15, 16, 17, 18 constitut...

Understanding Molar Concentration: A Key Concept in Chemistry

 Understanding Molar Concentration: A Key Concept in Chemistry Chemistry is the science that deals with the properties, structure, and composition of matter. One crucial concept in chemistry is molar concentration, which plays a crucial role in many chemical calculations, including stoichiometry, dilution, and reactions. In this blog post, we will delve into the fundamentals of molar concentration and explore its significance in chemical reactions and laboratory experiments. What is Molar Concentration? Molar concentration, also known as molarity, is a measure of the amount of solute dissolved in a given volume of solution. It is defined as the number of moles of solute per liter of solution and is denoted by the symbol "M." The molar concentration of a solution is determined by dividing the number of moles of solute by the volume of the solution in liters. The formula for molarity is Molarity (M) = moles of solute / volume of solution (in liters) For example, if you dissolve...

The Heat is On: Understanding the Significance of Melting Points

 The Heat is On: Understanding the Significance of Melting Points Melting point  What is Melting point  Melting point is a fundamental physical property of a substance, which is defined as the temperature at which a solid substance transforms into a liquid state at atmospheric pressure. This is a critical property because it can be used to identify a pure substance, to determine its purity, and to understand its behavior under varying conditions of temperature and pressure. Melting point is a characteristic property of a substance, which means that it is unique to that substance and does not depend on the size or shape of the sample. However, the melting point may vary slightly depending on the conditions under which the measurement is taken, such as the rate of heating, the size of the sample, and the purity of the substance. Therefore, the melting point of a substance is usually reported as a range of temperatures rather than a single value. The melting point of a subst...
