Match the word in Column 1 to its definition in Column 2. Each answer can only be used once. A)An atom differing from another atom of the same element in the number of neutrons in its nucleus B)A type of emission spectrum showing a series of lines separated by black areas C)A particle with no electrical charge that is one of the basic structures in the nucleus of an atom D)The state in which an atom absorbs energy and an electron moves from a lower to a higher energy level E)A negatively charged particle that is one of the fundamental structural units of the atom F)Light emitted from a source and separated into its component colors or frequencies G)The number of protons in the nucleus of an atom H)The sum of the number of protons and neutrons in the nucleus of an atom I)The path of electrons as they move around the nuclei of atoms J)A positively charged particle that is one of the basic structures in the nucleus of an atom -Isotope

The minerals found in different soil samples cannot effectively be used to determine whether or not they have the same origin.

The investigator should not try to remove trace paint evidence found on a tool but package the tool for laboratory examination instead.

The first step in a forensic soil comparison is analysis of the size of the particles.

After the paint has been applied to a surface, the solvent evaporates.

A thorough comparison of paint must include a chemical analysis of the paint's pigments and ________ composition.

The number of protons in the nucleus of an atom is called the atomic mass number.
