The periodic table.
Periodic Table
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.
Synthetic Elements are used in smoke detectors.
Chemical energy in gasoline becomes useful when we run our vehicles. In wood, it becomes useful when we burn it to heat our homes. In foods, it becomes useful when we eat the food.
Elements can not be made into simpler substances even by chemical reactions. Compounds can be broken down to simpler substances and eventually to elements. One useful observation is that an element will burn to give only one product, whereas a compound will give more than one.
The way that elements are arranged on the Periodic Table tells you some properties of the elements and how they relate to other elements. Elements in the same group (column) will exhibit some similar chemical properties, because their outer electron configurations are the same, for example.

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.
