How does the concept of quantization apply to the vibrational energies of atoms?

In summary, the conversation discusses the concept of quantized energy in atoms. The first paragraph explains that an atom's energy is limited to certain values, while the second paragraph mentions that an atom can change energy levels. The person is confused about how an atom with limited energy values can change energy levels. The explanation given is that the energy is lost or gained in discrete, non-divisible amounts, similar to a quantized waveform.

I am not understanding this def from the following paragraphs...

The book says...
The vibrational energies of an atom are said to be quantized, that is the possible ernergies are limited to certain values...

If a vibrating atom changed energy, say from 3hv to 2hv (from the equation E = hnv), it would decrease in energy by hv and this energy would be emitted as light energy...

Ok this is what I am not understanding... the first paragraph said that an atoms energy is limited to certain values...
the second paragraph said that an atom can change energy levels...

So how can an atom with " limited" energy values change energy levels...?

This is what I am thinking the first paragraph is saying... if an atom has a certain energy of n then this atom can not have energy less than or greater than its given n value... what am I not understanding?

They just mean that that particular amount of energy is lost by the smallest non-divisible number/factor.

If you thought of an atom as a function, and input a photon, you would not get out 1/2 a photon when that energy is released. Also, you can not fire a 1/2 photon into it. The photon is "quantized". Rather than using a continuous set of values, they use discrete sets.

A good example is:

The red wave is continuous, and the blue is quantized.

What is the definition of "Chem Definition (Quantized)"?

Chem Definition (Quantized) refers to the concept that certain properties of matter, such as energy and momentum, can only exist in discrete, specific values rather than a continuous spectrum. This is a fundamental principle in quantum mechanics.

How does quantization affect the behavior of atoms and molecules?

Quantization affects the behavior of atoms and molecules by restricting their energy levels to specific, discrete values. This leads to the formation of distinct energy levels and the absorption and emission of quantized packets of energy called photons.

What are some real-world applications of quantization?

Quantization has many real-world applications, such as in electronic devices like computers and smartphones where the quantized nature of electrons allows for the creation of digital signals. It is also essential in the development of lasers, solar cells, and medical imaging technologies.

How does quantization relate to the uncertainty principle?

Quantization is closely related to the uncertainty principle, which states that it is impossible to know both the exact position and momentum of a particle at the same time. This is because the act of measuring one property affects the other, and the quantized nature of energy and momentum adds to this uncertainty.

Are all properties of matter quantized?

No, not all properties of matter are quantized. For example, mass and volume are continuous properties that can take on any value. However, other properties such as energy, momentum, and spin are quantized. The extent of quantization varies depending on the specific property and its corresponding physical laws.
