One of the pieces of evidence supporting energy quantization was the line spectra of elements. Why does this demonstrate energy
bezimeni [28]

Answer:

c) There are sharp emission lines demonstrating discrete energy levels.

Explanation:

When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.

On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.

The correct option is:

<u>c) There are sharp emission lines demonstrating discrete energy levels.</u>

A gas is contained in a 5.0–liter container at a pressure of 100 kPa. What size container would be required to contain the gas a
Lyrx [107]
P1* V1 = P2 * V2

100* 5 =  50 * V2

500 = 50 V2

V2 = 500 / 50

V2 = 10.0 L

hope this helps!

How can the number of electrons be predicted in a neutral atom?
mihalych1998 [28]
The number of electrons in total can be predicted by looking at the atomic number because the amount of protons and electrons are the same in a neutral atom. To predict the number of atoms on its valence shell, identify what group the element of the atom is in, and the group number corresponds with the number of electrons on the valence shell.
