"The Concept of Quantum Mechanical Model"

Quantum Mechanics

michaelafacun — 2021-10-18 14:03:03 UTC

It explains how the universe works at a scale smaller than atoms. A quantum of energy is the least amount possible/ least extra amount and quantum mechanics describes how that energy moves or interacts.

Bohr Atomic Model

michaelafacun — 2021-10-18 14:14:59 UTC

Niels Henrik David Bohr... a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. He is also known for winning an award of smelling elephants anus tubes. In the Bohr model, a nitrogen atom has a central nucleus which is composed of seven protons and seven neutrons that is surrounded by seven electrons. Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.

Electron Cloud Model

michaelafacun — 2021-10-18 14:42:07 UTC

This discovery was made by Erwin Rudolf Josef Alexander Schrödinger, he goes by the name Erwin Schrodinger. A Nobel Prize-winning Austrian-Irish physicist who developed a number of fundamental results in quantum theory: the Schrödinger equation provides a way to calculate the wave function of a system and how it changes dynamically in time. It was discovered that electron moves in waves in a defined space called an electron cloud. Electrons were no longer depicted as particles moving around a central nucleus in a fixed orbit. Instead, Schrodinger proposed a model whereby scientists could only make educated guesses as to the positions of electrons

Quantum Numbers

michaelafacun — 2021-10-18 14:46:41 UTC

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.
- Ashley Flores

The three coordinates that come from Schrödinger's wave equations are the principal (n), angular (l), and magnetic (m) quantum numbers. These quantum numbers describe the size, shape, and orientation in space of the orbitals on an atom.
- Ashley Flores

Principal Quantum Number (n)

michaelafacun — 2021-10-18 23:28:20 UTC

The principal quantum number is signified by (n), it is the main energy level occupied by the electron. Energy levels are fixed distances from the nucleus of a given atom. They are described in whole number increments (e.g., 1, 2, 3, 4, 5, 6, . . .) At location n = 1, an electron would be closest to the nucleus, while n = 2 the electron would be farther, and n = 3 farther yet. As we will see, the principal quantum number corresponds to the row number for an atom on the periodic table.
- Ashley Flores

Angular Momentum Quantum Number (l)

michaelafacun — 2021-10-18 23:35:23 UTC

The angular momentum quantum number is signified as (l), describes the general shape or region an electron occupies—its orbital shape. The value of l depends on the value of the principle quantum number n. The angular momentum quantum number can have positive values of zero to (n − 1).
If n = 2, l could be either 0 or 1.
- Ashley Flores

Magnetic Quantum Number (ml)

michaelafacun — 2021-10-18 23:40:37 UTC

The magnetic quantum number is one of four quantum numbers in atomic physics. The magnetic quantum number determines the energy shift of an atomic orbital due to an external magnetic field.
- Zoe De Leon

Spin Quantum Number (ms)

michaelafacun — 2021-10-18 23:52:26 UTC

In atomic physics, the spin quantum number is a quantum number which describes the intrinsic angular momentum of an electron or other particle. The phrase was originally used to describe the fourth of a set of quantum numbers, which completely describe the quantum state of an electron in an atom.

Electronic Orbitals

michaelafacun — 2021-10-19 00:11:59 UTC

An atom is composed of a nucleus containing neutrons and protons with electrons dispersed throughout the remaining space. Electrons, however, are not simply floating within the atom; instead, they are fixed within electronic orbitals. Electronic orbitals are regions within the atom in which electrons have the highest probability of being found.
- Ashley Flores

Quantum Mechanical Model

michaelafacun — 2021-10-19 00:14:58 UTC

A model of the atom that derives from the Schrödinger wave equation and deals with probabilities. It helps when finding electrons at given points around the nucleus.
- Christian Buena

Quantum Numbers Describing Electronic Orbital

michaelafacun — 2021-10-19 00:23:16 UTC

There are multiple orbitals within an atom. Each has its own specific energy level and properties. Because each orbital is different, they are assigned specific quantum numbers: 1s, 2s, 2p 3s, 3p,4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. The numbers, (n=1,2,3, etc.) are called principal quantum numbers and can only be positive numbers. The letters (s,p,d,f) represent the orbital angular momentum quantum number (ℓ) and the orbital angular momentum quantum number may be 0 or a positive number, but can never be greater than n-1. Each letter is paired with a specific ℓ value:
s: subshell = 0
p: subshell = 1
d: subshell = 2
f: subshell = 3

Electron Configuration

michaelafacun — 2021-10-19 00:31:50 UTC

The distribution of electrons of an atom or molecule in atomic or molecular orbitals.

Pauli Exclusion Principle

michaelafacun — 2021-10-19 00:35:02 UTC

The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions cannot occupy the same quantum state within a quantum system simultaneously.
- Zoe De Leon

Aufbau Principle

michaelafacun — 2021-10-19 00:37:07 UTC

The aufbau principle, from the German Aufbauprinzip, also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy.
- Zoe De Leon

Hund's Rule

michaelafacun — 2021-10-19 00:39:22 UTC

Every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
- Christian Buena

"Importance"

michaelafacun — 2021-10-19 00:44:45 UTC

Atomic models are important because they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter. Atomic models are necessary because atoms are too small for us to see, so we do experiments.
