Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Atomic Mass by Dulong Petit’s Law In previous articles, we have studied Cannizzaro’s method and law of isomorphism method to determine atomic mass. In this article, we shall study to calculate atomic mass by Dulong Petit’s law. Specific Heat: The amount of heat […]
Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Law of Isomorphism Method In the last article, we have studied determination of atomic mass by Cannizzaro’s method. In this article, we shall study the law of isomorphism and its use to find the atomic mass of a substance. This law was given […]
Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Cannizzaro’s Method In the last article, we have studied the concept of atomic mass and to calculate the average atomic mass. In this article, we shall study the Cannizzaro’s method for determination of atomic mass. This method was proposed by Cannizzaro, Stanislao (1826-1910), […]
Science > Chemistry > Concept of Atomic Mass and Equivalent Mass > Concept of Atomic Mass The smallest particle of an element which can take part in a chemical reaction is called an atom. According to Dalton’s atomic theory atom is the smallest particle of an element which is indivisible. In modern research, it is proved that […]
Science > Chemistry > Solid State > Radius Ratio and its Significance The ratio of the radius of cations (r+) to the radius of the anion (r–) is known as the radius ratio of the ionic solid. The significance of radius ratio: It is useful in predicting the structure of ionic solids. The structure of […]
Science > Chemistry > Solid State > Tetrahedral Voids and Octahedral Voids In this article, we shall study two types of voids formed during hexagonal closed packing namely, a) Tetrahedral voids and b) octahedral voids. Let us consider a closed pack hexagonal packing in the first layer as shown. There are empty spaces between the […]
Science > Chemistry > Solid State > Packing in solids In this article, we shall study the different types of close packing of the constituent particles in solids. The Principle of Packing in Solids: In a crystal particle (atoms, molecules or ions) occupy the lattice points in the crystal lattice. These particles may be of […]
Science > Chemistry > Solid State > Numerical Problems on Type of Crystal Structure In this article, we shall study to solve problems to calculate the atomic radius, the distance between atoms in the unit cell and to decide the type of crystal structure. Example – 01: A naturally occurring gold crystallizes in face centred […]
