Planck’s Quantum Theory: Quantization of Energy

In this chapter, you will learn about the Planck’s quantum theory. Before going to learn about this theory, we will understand some few things. The wave nature of electromagnetic radiation could successfully explain some of the experimental phenomenon such as…

Drawbacks of Bohr’s Atomic Model

In this chapter, we will understand the drawbacks of Bohr’s atomic model in detail. Niels Bohr’s atomic model or theory successfully explained in a very systematic way the spectra of hydrogen atom and hydrogen like ions such as He+, Li2+,…

Representation of various orbits round the nucleus under Bohr's atomic model.

Bohr’s Atomic Model: Postulates

In this chapter, we will explore Bohr’s atomic model and its postulate. We will also see the derivation of radius of Bohr’s orbit, velocity of an electron, and energy of an electron in each orbit. Rutherford’s nuclear model of the…

Types of spectrum

What is Spectrum: Types of Spectrum

A spectrum is the impression or pattern formed on a screen when electromagnetic radiation of particular wavelengths is analyzed and dispersed using a prism or diffraction grating. In simple words, a series of coloured bands (wavelengths) produced when light is…

Electromagnetic spectrum

Electromagnetic Spectrum: Definition, Examples

Electromagnetic spectrum is the arrangement of all the electromagnetic radiations or waves in the increasing order of their wavelengths or decreasing order of their frequencies. In simple words, the electromagnetic spectrum describes the range of many electromagnetic radiations, which differ…

Wave nature of electromagnetic radiation.

Wave Nature of Electromagnetic Radiation

In this chapter, we will understand the wave nature of electromagnetic radiation with its definition, characteristics, and examples. We know that light is an important form of energy. Isaac Newton proposed the corpuscular theory of light, which regarded the light…

What are Isotones: Definition, Examples

The atoms of different elements containing the same number of neutrons, but different atomic number (or different number of protons and electrons) are called isotones. In simple words, isotones are atoms or nuclei of different elements that contains an identical…

Structure of three isotopes of carbon.

Isotopes: Definition, Meaning, Examples, Uses

All the atoms of a particular chemical element have the same number of protons in their nuclei, but the number of neutrons may be different. Such atoms have the same atomic number, but mass numbers are different because of a…
