Quantum Numbers (Principal, Azimuthal, Magnetic & Spin) - Definition, Detailed Explanation with Videos
Table of Contents What are Quantum NumbersRecommended VideosPrincipal Quantum NumberAzimuthal Quantum NumberMagnetic Quantum NumberElectron Spin Quantum NumberSummary Quantum numbers can be used to describe the trajectory and the movement of an electron in an atom. The quantum numbers of all the electrons in a given atom, when combined, must comply with the Schrodinger equation. What are Quantum Numbers? The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers. There are four quantum numbers, namely, principal, azimuthal, magnetic and spin quantum numbers. The values of the conserved quantities of a quantum system are given by quantum numbers. Electronic quantum numbers (the quantum numbers describing electrons) can be defined as a group of numerical values which provide solutions that are acceptable by the Schrodinger wave equation for hydrogen atoms. Quantum Numbers and Atomic Orbitals Four quantum numbers can be used to compl...
Isotopes and Isobars | Difference between isotopes and isobars
What are Isobars? Isobar is that element which differs in the chemical property but has the same physical property. So, we can say that isobars are those elements which have a different atomic number but the same mass number. Their chemical property is different because there is a difference in the number of electrons. It has the same atomic mass but different atomic no. Because an additional number of neutrons compensates the difference in the number of nucleons. The example of two Isotopes and Isobars is iron and nickel. Both have the same mass number which is 58 whereas the atomic number of iron is 26, and the atomic number of nickel is 28. What are Isotopes? Let us take an example of two things which have the same colour, same physical appearance, such that you cannot distinguish between these two. But when you measure the weight of these two things then you find that it is different. You can relate the concepts of isotopes with this example. As we all know that atoms are made up o...
