### Understanding Chemical and Nuclear Reactions **Question 2: (Multiple Choice Worth 4 points)** A student listed the characteristics of chemical and nuclear reactions. #### Chemical and Nuclear Reactions | X | Y | |---|---| | Changes the identity of the element | Does not change the identity of the element | **Which of these statements best explains the identity of Reaction X?** - ☐ It is a nuclear reaction because the identity of elements changes when there is a change in the number of protons and neutrons. - ☐ It is a chemical reaction because the identity of elements changes when there is a change in the mass of the atoms involved. - ☐ It is a chemical reaction because the identity of elements changes when there is a change in the overall energy of the system. - ☐ It is a nuclear reaction because the identity of elements change when there is a change in the number of outermost electrons. ### Explanation: In the provided table, Reaction X is characterized by a change in the identity of the element. To understand this identity change, it is essential to differentiate how chemical and nuclear reactions function: - **Nuclear reactions** involve changes in the nucleus of an atom, affecting protons and neutrons and resulting in the transformation of one element into another. - **Chemical reactions** involve changes in electron arrangements around the nucleus but do not affect the nucleus itself, meaning the identity of the element remains the same. Thus, the most accurate explanation for Reaction X is related to nuclear reactions where the identity of elements changes due to a change in the number of protons and neutrons in the nucleus.
