The Aufbau Principle, Salient Features and Exception.

The Aufbau principle states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy level before occupying higher-energy levels. It is a physical principle that states that electrons fill atomic orbitals of the lowest available energy level before occupying higher energy levels. What is mean by...Read More

Avogadro’s Law, Mathematical Representation with Examples for Understanding.

Avogadro’s law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. This means that if you have two containers, one filled with hydrogen gas and the other filled with oxygen gas, and both containers have the same volume and temperature and pressure, then they will...Read More

Boyle’s Law, Formula, Derivatives, and Some Examples.

Boyle’s law is a gas law that describes the relationship between pressure and volume of a confined gas. Such a law states that the pressure of a gas is inversely proportional to its volume at constant temperature and mass. This means that if the pressure of a gas is increased, its volume will decrease, and...Read More

Spinning into the Quantum Realm: Unraveling the Secrets of Spin Quantum Number.

The spin quantum number, also known as the electron spin quantum number, is the fourth quantum number that describes an electron. It is denoted by the symbol ms. The spin quantum number describes the intrinsic angular momentum of an electron, which is the rotation of the electron around its own axis. What is Spin Quantum...Read More

The Magnetic Quantum Number (“ml”),Properties and FAQs.

The magnetic quantum number (ml) is one of four quantum numbers that describe the state of an electron in an atom. It determines the orientation of the orbital, which is a region of space where there is a high probability of finding the electron. What do You Know About Magnetic Quantum Number? The magnetic quantum...Read More

Know the Azimuthal Quantum Number (l), Properties and FAQs.

The azimuthal quantum number is one of the four quantum numbers used in quantum mechanics to describe the behavior of electrons within atoms. It provides information about the shape of an electron’s orbital and the possible values of its orientation in three-dimensional space. The possible values of this quantum number are 0 to n-1, where n...Read More

Principal Quantum Number, Important Properties and FAQs

The principal quantum number (often denoted as “n”) is one of the four quantum numbers used to describe the characteristics and behavior of electrons within atoms in the framework of quantum mechanics. It primarily provides information about the energy level, or shell, in which an electron resides within an atom. Principal Quantum Number? The principal...Read More

Fuel cell and its important applications.

Any type of fuel is a source of energy. A fuel cell is a device, which can convert the chemical energy of a fuel such as hydrogen directly into clean electrical energy by a process known as electrochemical reactions. Fuel cell: A fuel cell is a device, which can convert the chemical energy of a...Read More

Cathode and anode in the primary and secondary battery.

A battery that is being used for power supply is basically a galvanic or voltaic cell. In a cell chemical energy is converted into electrical energy by a process known as an Oxidation -Reduction reaction or redox reaction. For the working of a battery an anode, cathode, and electrolyte are required. Cathode and anode are...Read More
