Question

explain 4 things:::-
1.)Atoms are composed of ?
2.)Quantum mechanics
3.)Schrodinger equation
4.)wave function​

Answer 1

Answer:

1.Atoms consist of a nucleus made of protons and neutrons orbited by electrons.

2.Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.

3.The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system. It is a key result in quantum mechanics, and its discovery was a significant landmark in the development of the subject.

4.A wave function in quantum physics is a mathematical description of the quantum state of an isolated quantum system.

Answer 2

ANSWER⤵️

ATOMS ARE COMPOSED OF :::-

• PROTONS- positively charged,

$\pink{mass:- 1.6726 \times {10}^{ - 27} kg}$

• NEUTRONS - neutral,

$\orange{mass:- 1.6750 \times {10}^{ - 27} kg}$

• ELECTRONS- negatively charged,

$\red{mass:- 9.1096 \times {10}^{ - 31} kg}$

QUANTUM MECHANICS :::-

Erwin Schrödinger derived a complex mathematical formula to incorporate the wave and particle characteristics of electrons.

Wave behaviour is described with the wave function ψ.

The probability of finding an electron in a certain area of space is proportional to ψ^2 and is called electron density.

SCHRODINGER EQUATION:::-

• Schrodinger combined the idea that an electron has wave properties with classical equations of wave motion to give a wave equation for the energy of an electron in an atom.

• wave equation (Schrodinger equation) give the series of solutions called wave function (ψ).

WAVE FUNCTION:::-

• only certain values of ψ are allowed.

• each ψ corresponds to a certain energy.

• the probability of finding an electron at a particular point with respect to the nucleus is given by ψ^2.

• each energy state corresponds to an orbital.
