describe why emission spectroscopy is a helpful tool in determining the identity of materials in fields like forensic science

Emission spectroscopy is a helpful tool in determining the identity of materials in fields like forensic science because it has the ability to identify and characterize the elements in a sample obtained for forensic analysis. It accomplishes this by making the sample go through a medium that can disperse the atoms and ions in the element at specified wavelengths.

Explanation:

Atomic emission spectroscopy is a method used in the laboratory to characterize the elements found in a sample needed for a study when they pass through a flame. Inductively coupled plasma is a type of atomic emission spectroscopy which has the ability to excite the components of an element at specific wavelengths when they undergo electromagnetic radiation.

This method can identify the isotopes, atom, and ions present in a sample. This is useful in forensics as it aids the identification of the elements in the sample.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
