Summarizing Atomic Structure Write a brief passage describing a neutral atom of
nitrogen-14 (N-14). Describe the number of
protons, neutrons, and electrons in the atom,
where each type of particle is located, and how
the terms atomic number, mass number, and
atomic mass are related to the particles. Use the
periodic table to help you.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
