Class 11

Litre elements and compounds have their unique densities associated with them. The density of a matter is one of its physical characteristics. In simpler words, the ‘heaviness’ of objects with a constant volume can be said to be a qualitative measurement of the density of that object. So it can be said that the compactness […]

The de Broglie waves or matter waves refer to the properties of matter that vary in time or space while showing a wave-like behaviour. They are named after the French physicist Louis de Broglie. In 1924, for the first time, Louis de Broglie proposed the wave-like nature of the electron and said that all matter

De Broglie’s hypothesis is one of the most fundamental theories that give a direction to quantum mechanics from classical physics. It describes the dual nature of matter, i.e., matter can behave like both particles and waves. The phenomenon of a beam of light with diffraction, just like a wave, is explained by this theory. In

John Dalton FRS was an English chemist, physicist and meteorologist. He is known for introducing the atomic theory.  The law of conservation of mass and the law of definite proportions, according to Dalton, might be explained using the concept of atoms. All matter, he suggested, is made up of small indivisible particles known as Atoms,

The wave-like nature of subatomic particles was a great debate over the years, and it was put to an end by the physicist Erwin Schrodinger. He gave a mathematical equation to identify the wave nature of subatomic particles and introduced a new subject of wave mechanics where the energy of atomic orbitals could be studied.

Atoms are the fundamental building pieces of everything you see around you, including the screen you’re currently viewing, your study table, and your books. Such is nature’s incredible strength and the underlying character of these particles. Despite the salient features of Dalton’s Atomic Theory, the discovery of subatomic particles such as electrons, protons, and neutrons,

Before we start with the concept of an atom, it is extremely important to clear all our doubts about an atom. An atom is the smallest particle that makes up matter. It can not be divided further. An atom consists of a proton, neutron, and electron. A proton has a positive charge, a neutron has

Introduction The atoms have more than 100 different chemical elements that make up all matter in the universe. These atoms can be found in both pure form and mixed known as chemical compounds. Any pure element is completely made up of the atoms that make up that element, and each element’s atoms are different. The

The matter is categorized into three types based on its physical properties. Solid Liquids Gas We will learn about solids and their properties in this section. The topic of solids and their classification is very important in chemistry. Because the molecules of solid substances are densely packed, solids have a specific volume and a particular

Ethers are chemical molecules in which either two alkyl or aryl groups or one alkyl and one aryl group are joined by an oxygen atom. Ethers are a common linkage in carbohydrates and lignin, and they’re considerably more abundant in biochemistry. In this classification of ethers, we will study the classification of ethers examples. We
