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.
