the chemical and physical behavior of metallic elements
The star's absorption spectrum would be most useful in determining its chemical composition. By studying the specific wavelengths of light that are absorbed by elements in the star's atmosphere, scientists can identify the presence of different elements and molecules.
The periodic table is arranged in order by atomic number, the number of protons in the nucleus of the atom. The columns of the table represent elements with similar chemical characteristics. You could arrange the elements in alpha order, but it wouldn't be very useful.
The modern periodic table is useful because it organizes elements based on their atomic number and similar chemical properties. This arrangement helps predict the behavior of elements, their reactivity, and their physical properties. It also provides a systematic way to study and understand the relationships between different elements.
Percent composition is a useful tool in chemistry because it gives you insight into the relative abundance of elements in a compound. By knowing the percent composition, you can predict the physical and chemical properties of the compound and use it to calculate other information, such as molar mass or stoichiometry in reactions.
periodic table
periodic table. The periodic table provides a concise and organized overview of all the known elements, including their atomic number, atomic mass, and other key properties. It allows scientists to quickly access information about each element, such as its electron configuration, valence electrons, and chemical reactivity.
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.

Reddit can be a useful source of information, but it is important to verify the credibility of the information shared on the platform as it is user-generated content and may not always be accurate or reliable.
Polonium and radium are two natural chemical elements, highly radioactive, solid, metals, rare, expensive, dangerous, with some useful applications etc.
