Gamma Decay, Process, Examples and Applications

Gamma decay, also known as gamma emission or gamma radiation, is a type of radioactive decay involving the release of high-energy gamma-ray photons from an unstable atomic nucleus. Unlike alpha decay and beta decay, gamma decay does not change the atomic number (Z) or mass number (A) of the nucleus. Instead, it occurs to bring...Read More

Beta Decay, Types, Examples, Fermi’s Theory and uses

Beta decay is a type of radioactive decay that involves the transformation of an unstable atomic nucleus into a more stable one by the emission of either a beta-minus (β-) particle (an electron) or a beta-plus (β+) particle (a positron). This process allows for a change in the atomic number (Z) while conserving the mass...Read More

Alpha Decay, Process, Applications, and FAQs

Alpha decay is a type of radioactive decay in which an unstable atomic nucleus emits an alpha particle (α-particle), which consists of two protons and two neutrons. This process results in a decrease in both the atomic number and mass number of the nucleus. What is Alpha Decay? Alpha decay is a type of radioactive...Read More

The Anti-Markovnikov Rule, Definition, Significance and Applications

The Anti-Markovnikov Rule, also known as the Kharasch Rule, is a principle in organic chemistry. It describes the regioselectivity of certain chemical reactions, specifically addition reactions to unsymmetrical alkenes (carbon-carbon double bonds) in the presence of certain reagents, typically hydrogen halides (H-X, where X is a halogen like chlorine, bromine, or iodine). The Anti-Markovnikov Rule...Read More

Hund’s Rule, Definition, and Applications.

Hund’s rule states that electrons fill each orbital singly in degenerate orbitals before pairing up. Degenerate orbitals are orbitals of the same energy level. While Hund’s rule is a fundamental concept in chemistry, it doesn’t necessarily manifest in “real-time” events like a visible phenomenon. Instead, it influences the behavior of electrons in atoms and molecules....Read More

The Markovnikov Rule, Exceptions and Applications.

The Markovnikov Rule, also known as Markovnikov’s addition, is a fundamental concept in organic chemistry that helps predict the outcome of electrophilic addition reactions to unsymmetrical alkenes or alkynes. It states that in the addition of a protic acid (such as HCl or HBr) or other electrophiles to an unsymmetrical alkene or alkyne, the electrophile...Read More

The Pauli Exclusion Principle, Real Time Examples and Some Exception.

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. The four quantum numbers are: What is the Pauli Exclusion Principle? The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. The four...Read More

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

Gay-Lussac’s Law, Examples, Applications, and Limitations.

Gay-Lussac’s law states that the pressure of a given mass of gas is directly proportional to its absolute temperature when the volume is kept constant. This means that if the temperature of a gas is increased, its pressure will increase proportionally. Conversely, if the temperature of a gas is decreased, its pressure will decrease proportionally....Read More

Charles’s Law, Formula, and Key Points to Know.

Charles’s law states that the volume of a given mass of gas is directly proportional to its absolute temperature when pressure is kept constant. This means that if the temperature of a gas is increased, its volume will increase proportionally. Conversely, if the temperature of a gas is decreased, its volume will decrease proportionally. Charles’s...Read More
