## What are the two aspects of wave mechanical model of atom?

The wave-mechanical theory proposes that each electron circling an atom’s nucleus occupies a specific orbital and spins a certain direction, but the orbital is like a cloud or wave of energy, not the ring you might imagine thinking about the earth’s orbit around the sun.

How can the atomic orbital be described in the quantum mechanical wave model of the orbitals?

In quantum mechanics, an orbital of the atom is considered as a region where the chances of locating an electron are highest.

What is the wave mechanical model of an atom required to explain?

the wave mechanical model uses probability to predict the location of an electron and says electrons exist in clouds. it is different because it describes the atom mathematically and we don’t use it to draw atoms because the orbitals are difficult to draw.

### Which atom model has orbitals?

the Bohr model
Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have.

What are the main points of quantum mechanical model?

What are important features of the quantum mechanical model of atom? The important features are: (i) The energy of electrons in atoms is quantized. (ii) The existence of quantized electronic energy levels is a direct result of the wave like properties of electrons.

What was Schrodinger’s model called?

the quantum mechanical model of the atom
Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves.

#### What are the main features of quantum mechanical model of atom?

Features of quantum mechanical model of atom

• The electrons in an atom have only quantized value of energy.
• These quantized values of energy are obtained from the solution of Schrodinger Wave Equation.
• The wave function Ψ is simply a function of coordinates of the electron and has no physical significance as such.

What did Bohr’s theory explain?

In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Bohr’s model explained why atoms only emit light of fixed wavelengths, and later incorporated the theories on light quanta.

What does Schrodinger’s Cat prove?

“Schrodinger’s Cat” was not a real experiment and therefore did not scientifically prove anything. Schrodinger constructed his imaginary experiment with the cat to demonstrate that simple misinterpretations of quantum theory can lead to absurd results which do not match the real world.

## Which is the wave mechanical model of the atom?

We will now explore a general picture of this model, which is called the wave mechanical model of the atom. In the Bohr model, the electron was assumed to move in circular orbits. In the wave mechanical model, on the other hand, the electron states are described by orbitals. Orbitals are nothing like orbits.

How are orbitals used in the quantum mechanical model?

Recall that in the Bohr model, the exact path of the electron was restricted to very well-defined circular orbits around the nucleus. An orbital is the quantum mechanical refinement of Bohr’s orbit.

How did Erwin Schrodinger describe the quantum mechanical model of the atom?

Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. . , represents the probability of finding an electron in a given region within the atom. An atomic orbital is defined as the region within an atom that encloses where the electron is likely to be 90% of the time.

### How is the wave equation related to quantum mechanics?

Quantum mechanics is based on Schrödinger’s wave equation and its solution. The solution of the wave equation brings the idea of shells, sub-shells and orbitals. The probability of finding an electron at a point within an atom is proportional to the |ψ| 2 at that point, where ψ represents the wave-function of that electron.
