Atomic and molecular masses

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

There are many notations that are used by a chemist to determine and summarize atomic constituents in a symbolic way. These notations include empirical formula, molecular formula, and structural formula. The molecular formula includes the chemical symbols of the different elements along with their numerical values which show their composition in a molecule. Unlike the

The term Brownian movement stands for the random zig-zag motion of a particle when it’s observed under a high-power ultra-microscope. It’s named after the Scottish Botanist Robert Brown, who explained the resemblance of this movement with pollen grains in water; hence it’s known as the Brownian movement. Later on, Albert Einstein wrote a paper on

Introduction  The strength and direction of magnetism in particular elements are referred to as the magnetic moment of the system. This term is related to the magnetic dipole moment of different elements. Being a vector quantity, the magnetic moment comes with direction and magnitude. For instance, an electron with its intrinsic spin property makes the

Atomic And Molecular Masses Introduction An atom is so small that it cannot be seen or separated. So, determining its real mass by weighing it is impossible. Avogadro’s law, also known as Avogadro’s principle or Avogadro’s hypothesis, is a gas law which states that the total number of atoms/molecules of a gas (i.e. the amount

Chemistry is the study of matter and thus the changes it undergoes in everyday activities. In essence,  the center of chemistry involves studying changes around our world. Let us discuss some basic ideas  of atoms, molecules, and therefore the matter they make–elements and compounds. The properties  of elements and compounds are determined by their structures.
