Read each question carefully and provide your answer in the space provided. Show all your work for calculations.
1. Which of the following statements best describes an isotope?
Atoms of the same element with different numbers of protons.
Atoms of the same element with different numbers of neutrons.
Atoms of different elements with the same mass number.
Atoms with a net positive or negative charge.
2. An atom that has gained electrons becomes a(n):
Cation
Anion
Isotope
Neutral atom
3. The atomic number of an element is determined by the number of in its nucleus.
4. Ions are formed when atoms lose or gain , resulting in a net electrical charge.
5. The mass number of an atom is the sum of its and .
6. Explain the difference between an ion and an isotope. Provide an example for each.
7. Carbon-12 and Carbon-14 are isotopes of carbon. Describe how they are similar and how they differ.
8. All atoms of a given element have the same number of neutrons.
True
False
9. A cation is an ion with a net negative charge.
True
False
10. Observe the atomic structure diagram below. Identify the subatomic particles and their charges. Then, explain how removing an electron from this atom would change its overall charge and classification.
