Atoms and Nuclei

There are two hydrogens and one oxygen atom in every water molecule because of the solid covalent connection that holds them all together: H2O. Water is the lightest in its gaseous form; it is significantly heavier in liquid form. Different qualities make it a valuable conductor of electricity. Water is colourless, tasteless, & tasteless; it […]

The energy level can be defined as the stable or constant energy state achieved by a system consisting of particles like atoms, electrons, etc. These states are highly important, especially in the quantum states of the particles. Energy levels are also referred to as energy states. The concept of energy level was used for the

An isotope of  an element has a standard atomic number but different molecular masses. An isotope of an element possesses almost similar chemical properties as other elements or other isotopes of that particular element. Isotopes have the same number of protons in their outer shell. They differ by the number of neutrons present in their

The hydrogen spectrum is a spectrum that is formed by the transfer of electric charge that passes through the gaseous molecules of the hydrogen. As the electric charge is discharged, it will dissociate the atoms of hydrogen into an excited state and proceed through different radiations. These radiations comprise spectral lines along with the well-defined

If we focus on our surroundings, we will find that all matter present in nature is formed by molecules or atoms, which have the property of absorbing energy and emitting it. This property is to move from its lower energy level to higher energy. When these molecules or atoms return to their original state, radiation

As we all know, an atom consists of protons, neutrons, and electrons. Protons and neutrons reside in the nucleus of an atom, and electrons spin around the nucleus. Electrons can move around, jump around and bind with other atoms. But they cannot do so in any manner and any position. They have fixed energy levels

Danish physicist Neils Bohr introduced the Bohr’s model of an atom in 1915. This discovery was the key to the journey towards understanding atoms. According to Bohr’s model, also called the Rutherford-Bohr model, an atom comprises a small positively charged nucleus orbited by negatively charged electrons. The modern Bohr’s model is built on quantum mechanics.

Hydrogen is the very first element of Henry Moseley’s modern periodic table. It is non-metal and consists of one electron and one proton. Every element in the periodic table has its properties, one of them being the emission of electromagnetic radiation. Whenever the electron of a hydrogen atom absorbs energy or radiation, it is called

During the discharge of electricity in a low-pressure tube consisting of hydrogen gas, the emission of radiation takes place. This radiation is further analyzed using a spectrograph, giving us a series of lines. This combined line spectrum is called the hydrogen atomic spectrum. Each line of this hydrogen atomic spectrum indicates a different wavelength of

Energy levels are the fixed ranges between which electrons can orbit. We have different orbits in which electrons revolve. By combining the energy quanta of Planck’s concept with Rutherford’s model of atoms of electrons orbiting the nucleus, Bohr arrived at his model.By combining energy quanta of Planck’s concept with Rutherford’s model of atom of electrons
