Nuclear Chemistry: Nuclear Chemistry I Quiz

Subatomic particles have clearly defined roles in an atom. The number of protons identifies an element. Adding or subtracting protons changes the identity of an element. For example, neon has 10 protons, but if you remove one, the element becomes fluorine. By contrast, adding or removing electrons does not alter the identity of the element. Changing the number of electrons affects the chemical reactivity of the element. Removing one of fluorine's nine electrons turns it into a fluorine ion. As such, when it comes to manipulating an atom's neutrons, the element is affected in a different way. There are reactions that involve atoms changing into other atoms. These processes takes place in the nucleus and are called nuclear reactions. This quiz is over simple nuclear chemistry. Refer to the diagram and images to aid in answering the questions. Using what you have learned, select the best answer to the choices.
