Atomic and molecular masses

The act of courtship is comparable to the establishment of bonds. Atoms move closer together, attract each other, and progressively lose a small portion of their mass to the other atoms. Hybridisation, or the study of bonding, is significant in chemistry. During bonding, what happens to the atoms? The concept of hybridisation holds the key […]

When Classical mechanics failed to apply in microscopic particles like electrons, protons, atoms, molecules, etc. since it ignored the concept of dual behaviour of matter, especially for subatomic particles and the uncertainty principle, the branch of science that deals with the dual behaviour of matter and interaction of subatomic particles, Quantum mechanics was introduced.  It

A vernier caliper is an instrument that is most commonly used for a variety of exact measurements. A vernier caliper is a tool used in the physics lab to precisely measure the lengths of small objects that would be impossible to do with a meter scale. A vernier caliper’s main use is to measure an object’s internal and external

Quantum numbers are a collection of numbers used to describe the position and energy of an electron in an atom. There are four types of quantum numbers: the principal, azimuthal, magnetic, and spin quantum numbers. They are used to determine the values of the conserved quantities in a quantum system. Electronic quantum numbers (the quantum

What is the quantum of charge? The quantum of charge helps in detecting the electronic control of an electron. It helps detect the smallest charge and how it helps in various applications and electric purposes. Quantum is an important concept in physics and chemistry, with quantum numbers describing the trajectory and the movement of the

Introduction The uncertainty principle, also known as the Heisenberg uncertainty principle or the indeterminacy principle, is a statement made by German physicist Werner Heisenberg in 1927. It states that an object’s position and velocity cannot be measured precisely at the same time, even in theory. In fact, in nature, the concepts of absolute position and

Introduction The uncertainty principle is without a doubt one of the most well-known parts of quantum mechanics, if not the most famous. It has frequently been cited as the greatest distinguishing aspect of quantum mechanics as compared to classical models of the physical world, and for good reason. The uncertainty principle (for position and momentum)

JEE Main 2024 Result Session 2 When the bond pair moves towards the more electronegative atom, it polarises a sigma bond. Polarisation occurs between two atoms with varying electronegativity. The electronegative atom receives only a partial negative charge, while the other atom receives a partial positive charge. Click here to know about Unacademy Aarambh 2024

Introduction Pauli’s Exclusion principle fundamentally enables us to comprehend the electron configurations in atoms and molecules, and it also explains the categorization of elements in the periodic table. The Pauli Exclusion Principle asserts that in a single atom, no two electrons will have an exact copy of the same quantum numbers (n, l, ml, and

Between 1803 and 1808, John Dalton proposed an atomic theory. According to this theory, an atom is the smallest indivisible particle, and it cannot be divided further. It almost explained everything related to atoms except their chemical activity. It could not conclude anything about atomic masses as well. Finally, scientists J.J. Thomson and Ernest Rutherford
