because it helps organizing and remembering the chemical facts.
I consider that this information is the electronegativity.
The unique light emission patterns of elements, known as their atomic spectra, can provide valuable information to scientists. By studying these spectra, scientists can identify elements present in a sample, determine their concentrations, and even understand the chemical and physical properties of the material under study. This information is used in various fields such as astronomy, environmental science, and materials science.
This question is based on chemistry. Halogens are useful elements. There are 5 halogens in the world.
One use of noble gases is in lighting, such as neon lights. Because noble gases are unreactive, they can be used in these applications as they do not readily form compounds or react with other substances, allowing for a stable and long-lasting light source.
The periodic table is the most useful source of information about the chemical elements. It organizes the elements based on their atomic number, electron configuration, and recurring chemical properties. It provides a wealth of information about each element, including its symbol, atomic weight, and various properties.

Spectroscope is a useful qualitative analysis tool because is it can analyze wavelengths what humans can't see especially infrared and ultraviolet radiation. Also since light has a different color of wavelengths; Scientist can find useful information such as chemical elements present at the source of the light.
Media is a source of information and can be very useful.
