Science > Chemistry > Third Row Elements > Hydroxides of Third Row Elements In this article, we shall study hydroxides of third row elements. Different types of hydroxides of third-row elements are classified according to their mode of dissociation. According to Arrhenius’s theory, the acid is the substance which gives H+ ions in an aqueous […]

Science > Chemistry > Third Row Elements > Oxides of the Third Row Elements A binary compound of an element with oxygen, in which the oxygen atom is electronegative is called an oxide. e.g. MgO, Al2O3, etc. The oxide in which Oxygen exhibits the normal oxidation state of -2 is called normal oxide. In this article, […]

Science > Chemistry > Third Row Elements > Molecular Solids of the Third Row in this article, we shall study the crystal structure of molecular solids of third perid of periodic table. Molecular solid: The substance in which lattice points are molecules which are held together by means of weak physical forces (van der Waal’s […]

Science > Chemistry > Third Row Elements > Metallic solids of the Third Row In this article, we shall study properties metallic solids of third row. The metallic bond is defined as the force of attraction that binds metal cations to a number of mobile or delocalized electrons within its sphere of influence which holds […]

Science > Chemistry > Third Row Elements > Concept of Metallic Bond and Metallic Solids In this article, we shall study the concept of metallic bond and metallic bonds in sodium, magnesium and aluminium crystals. Concept of Metallic Bond: The metallic bond is defined as the force of attraction that binds metal cations to a […]

Science > Chemistry > Third Row Elements > Oxidizing and Reducing Property of the Third Row Elements In this article, we shall discuss the trend in oxidizing and reducing property of third row elements. Oxidation: The process in which an atom, a molecule or an ion loses one or more electrons is called oxidation. It […]

Science > Chemistry > Third Row Elements > Metallic Character of Third Row Elements In this article, we shall study the trend im metallic character of third row elements. Metallic Character: The tendency of an atom to lose electrons to form positively charged ion is called its metallic character or electropositive character. Typically metals show […]

Science > Chemistry > Third Row Elements > Ionization Enthalpy of Third Row Elements In this article, we shall study trend in the ionization enthalpy of third-row elements. Ionization Enthalpy: The minimum energy required to remove the most loosely attached electron from the outermost shell of a neutral gaseous, isolated atom of an element in […]

Science > Chemistry > Third Row Elements > Introduction The elements are arranged in the order of increasing atomic numbers, in such a way that elements with similar properties fall in the same vertical column of the periodic table. There are eighteen vertical columns known as groups and seven horizontal rows are known as periods. A […]
