Science > Physics > Atoms, Molecule, and Nuclei > Hydrogen Spectrum The origin of spectral lines in the hydrogen atom (Hydrogen Spectrum) can be explained on the basis of Bohr’s theory. The hydrogen atom is said to be stable when the electron present in it revolves around the nucleus in the first orbit having the […]

In this article, we shall study Bohr’s Model of an atom, its merits, and demerits. To overcome the limitations of Rutherford’s model of an atom, […]
Science > Physics > Atoms, Molecule, and Nuclei > Rutherford’s Model of an Atom In this article, we shall study Dalton’s atomic theory, Rutherford’s model of an atom, its merits, and demerits. Dalton’s Atomic Theory: This theory was proposed by English chemist John Dalton in 1808. The main propositions of the theory are as follows: […]
Science > Chemistry > Physical Chemistry > Ionic Equilibria > Solubility Product In this article, we shall study the concept of solubility, solubility product, and its applications. Some ionic solids are highly soluble in water while others are almost insoluble in it. The solubility of ionic solid depends on lattice enthalpy of the salt and […]
Science > Chemistry > Physical Chemistry > Ionic Equilibria > Common Ion Effect In this article, we shall study the common ion effect and its applications. The phenomenon in which the degree of dissociation of any weak electrolyte is suppressed by adding a small amount of strong electrolyte containing a common ion is called a […]
