Explanation:
The given question is related to the concept of atomic spectra. Atomic spectra is a characteristic property of every element which is used to identify the element. It is produced when an atom absorbs or emits energy as electromagnetic radiation.
The correct option is A, i.e., each element is associated with a characteristic spectrum of radiation. This means that every element emits or absorbs radiation of a unique wavelength that is specific to that particular element.
The characteristic spectrum of radiation is the set of wavelengths at which an element emits or absorbs radiation. There are three types of atomic spectra:
1. Continuous spectrum: A continuous spectrum is produced when a solid, liquid or dense gas is heated and the atoms in the material emit radiation at all wavelengths. This type of spectrum is not specific to any particular element.
2. Emission spectrum: An emission spectrum is produced when an element is heated or excited with energy, and the electrons in the atom jump to higher energy levels. When these electrons fall back to their original energy levels, they emit energy as radiation. The wavelengths of this radiation are specific to that particular element.
3. Absorption spectrum: An absorption spectrum is produced when an element absorbs certain wavelengths of radiation. When white light is passed through a sample of a specific element, certain wavelengths of light are absorbed by the atoms in the material, leaving dark lines in the spectrum. These dark lines are specific to that particular element.
In summary, the correct option is A because every element is associated with a characteristic spectrum of radiation, which is used to identify the element.
