1. An atom that has gained one or more electrons is called a(n):
Cation
Anion
Isotope
Neutron
2. Atoms of the same element that have different numbers of neutrons are called:
Ions
Isotopes
Molecules
Compounds
3. The atomic number of an element is determined by the number of in its nucleus.
4. The mass number of an atom is the sum of its protons and .
5. A positive ion is called a .
6. All isotopes of an element have the same chemical properties.
True
False
7. An atom becomes an ion by gaining or losing protons.
True
False
8. Explain the difference between an ion and an isotope.
9. A neutral atom of an element has 17 protons and 18 neutrons. What is its mass number? If it gains one electron, what type of ion does it become?
10. Observe the image below. Identify the number of protons, neutrons, and electrons in each depicted atom. Then, determine if each is an ion, an isotope, or a neutral atom.
